Why Buy From Trinity NDT

We don't just sell dye penetrant chemicals — we use the same Ferrochem and Magnaflux penetrant systems every day in our own NABL and NADCAP-accredited laboratory, including for aerospace and oil and gas inspection work. That means the kit you buy from us is the same system we rely on for our own accredited testing, not a separate, lower-grade retail line.

We sell and supply dye penetrant chemical DPT kits conforming to ASTM E165 and ASTM E1417, and relevant ISO standards, with a certificate of conformance provided for each batch of materials.

Classification of Dye Penetrant Materials Based on ASTM E165

By penetrant type:

  • Type 1 (Fluorescent)
  • Type 2 (Visible Red)

By method of penetrant removal:

  • Method A (Water Washable)
  • Method B (Post Emulsifiable — Lipophilic)
  • Method C (Solvent Removable)
  • Method D (Post Emulsifiable — Hydrophilic)

By penetrant sensitivity:

  • Level ½ — Ultra low
  • Level 1 — Low
  • Level 2 — Medium
  • Level 3 — High
  • Level 4 — Ultra high

Sensitivity and penetrant type are selected based on the applicable specification, product code and the application of the component being tested.

FPI Line aerospace NDT Labs in Bangalore India

Portable Kits and Stationary FPI Line Equipment

Portable dye penetrant chemical kits suit on-site dye penetrant testing. For large production parts and higher sensitivity requirements, a stationary-type DPT system performs better. Trinity NDT supplies DPT/FPI inspection systems to the specifications demanded by aerospace companies, with post-emulsifiable and water-washable test systems designed to suit customer needs.

A typical stationary DPT system

A typical system consists of a series of tanks, sized around 1000 x 1000 x 600 mm, for the following functions:

  • Timers, hooters and electric circuitry for controlling operations
  • Water-washable fluorescent penetrant application and dwell
  • Post-emulsifiable fluorescent penetrant application and dwell
  • Water rinse station for pre-rinse
  • Water spray for post-rinsing of emulsified parts
  • Hot-air recirculating oven for drying components
  • Enclosed dust chamber for dry powder developer application
  • Black light chamber for examination

Liquid Penetrant Testing Accessories for Sale

Penetrant testing needs other accessories to perform the test and validate results. We supply the following at our Bangalore sales division — contact us for price, stock availability and delivery schedules.

UV Black Light Intensity Meter (Radiometer)

UV Black light Intensity Meter for NDT testing

Used for measuring ultraviolet (UV) or black light intensity. UV light meters need calibration, usually every six months, as per the applicable testing procedure or standard. Useful for checking the intensity of UV/black light bulbs in liquid dye penetrant testing. Comes with a sensor; the quality of the instrument and sensor both matter.

Lux Meter for Measuring Visible Light Intensity

For checking white light intensity, a lux meter is required, measuring visible light at wavelengths of 400nm to 700nm. Like UV meters, lux meters should be calibrated once every six months as per ASTM E165.

lux meter visible light meter for NDT testing

UV Goggle for UV Light Protection

UV light goggles for NDT testing - Penetrant and Magnetic Particle Testing

UV or black light emits a range of the ultraviolet spectrum. The wavelength range from 320nm to 400nm is generally considered safe, and UV goggles help filter out the harmful wavelengths emitted from UV/black lights used in NDT testing, protecting the inspector’s eyes during examination.

Aluminium Comparator Crack Test Block - Sales

Useful for testing penetrant sensitivity and comparing different penetrants. These blocks have multiple cracks that produce indications for verifying sensitivity, and are one of the most widely used calibration blocks for non-aerospace NDT applications — for aerospace work, TAM/PSM panels are more widely used. Run the block with each new penetrant batch to verify material quality.

Aluminium Comparator Crack Block

UV Black Lights for DPT/FPI Testing

UV Black Light Assembly for NDT testing

We supply UV light assemblies with LED and white light combinations, suited to fluorescent penetrant testing. Our UV lights emit a UV-A spectrum meeting relevant ASTM E3022 and ISO standards, supplied with the original test certificate and calibration report.

 

 

 

Filter for UV Lights

Filters are essential for removing harmful shorter wavelengths emitted by UV lights, making them safe for NDT inspection use. Fluorescent penetrant inspection should never be performed without a proper filter in place. 

Clean the filter regularly to maintain full UV intensity.

Frequently Asked Questions About Dye Penetrant Chemicals

What is included in a DPT testing chemical kit?

A standard DPT test kit includes a penetrant, a solvent cleaner and a developer, each supplied as a 420ml aerosol can. We also stock standard open cans for higher-volume use, and both visible (red) and fluorescent (yellowish-green) penetrant varieties.

What brands of dye penetrant chemicals do you stock?

We are the authorised Ferrochem dealer for Karnataka, and we also stock Magnaflux and MR Chemie make penetrants, cleaners and developers. We supply named Ferrochem products including CrackCheck FC911, FC931 and FC711.

How much does a DPT chemical kit cost?

A standard DPT kit (penetrant, cleaner and developer, 420ml aerosol cans) starts from our published price plus GST, ex-works from Peenya, Bangalore. Contact us on WhatsApp with your required quantity for a current quotation.

Can I collect chemicals from your office, or do you deliver?

Both. Ready stock can be collected the same day from our office in Peenya Industrial Area, Bangalore, and we also supply customers across India by courier or transport on request.

Are test certificates and MSDS provided with the chemicals?

Yes. A test certificate is provided for each batch of materials supplied, and a Materials Safety Data Sheet (MSDS) accompanies every sale.

What is the shelf life of dye penetrant chemicals?

Shelf life depends on the specific product and storage conditions; check the batch certificate and manufacturer's datasheet supplied with your order for the exact expiry date. Store penetrants, cleaners and developers in a cool, dry place away from direct sunlight to maximise shelf life.

How often does a UV light intensity meter need calibration?

UV light intensity meters (radiometers) and lux meters should be calibrated once every six months as per ASTM E165 and standard testing procedures, to ensure accurate verification of UV and white light intensity during fluorescent penetrant inspection.

What is an aluminium comparator crack block used for?

An aluminium comparator block has multiple cracks of known characteristics, used to verify and compare the sensitivity of a penetrant batch. Run the block with each new batch of penetrant to confirm material quality before using it on production parts. For aerospace applications, TAM/PSM panels are more commonly used instead.

Do you supply equipment for aerospace fluorescent penetrant inspection (FPI)?

Yes. We supply portable kits for on-site testing and stationary FPI line equipment and tank systems built to aerospace company specifications, including water-washable and post-emulsifiable fluorescent penetrant systems.

Can I order in bulk, and is there a minimum order quantity?

We supply both small quantities and bulk orders. Contact us on WhatsApp with your required quantity and we will confirm pricing, stock availability and any applicable minimum order quantity for your specific requirement.

What is the difference between Type 1 and Type 2 penetrants?

Under ASTM E165, Type 1 penetrants are fluorescent, viewed under UV/black light, and offer higher sensitivity. Type 2 penetrants are visible red dye, viewed in ordinary white light, and are typically used for on-site or lower-sensitivity applications.

Do you serve customers outside Bangalore?

Yes. While our office and stock are based in Peenya Industrial Area, Bangalore, we supply dye penetrant chemicals and accessories to customers in Hosur, Mysore and across India.
