Hot Air Oven

Curing, drying, ageing, annealing or any heat processing tests at higher temperatures .

Features

STD: IEC 60068-2-x,MIL-STD-810
TEMP: Ambient to +300 C

Salt Corrosion Test

Salt corrosion test is for accelerating real-world corrosion failures with EUTs. As the name implies, the test comprises different climates which are cycled automatically so the samples under test undergo the same sort of changing environment that would be encountered in the natural world.

Features

STD: IEC 60068-2-x, MIL-STD-810, ASTM B117 etc...
Specifications of the corrosion test chamber:
Volume: 900 litres
Salt spray test temperature range: Ambient to 50° C
Condensation: 1.5 ml ± 0.5 ml/80cm2/hr
High humidity/Wetting mode: 95 to 100% RH (Uncontrolled)
Drying mode: Ambient to 70° C
Internal Dimension: 1350mm*850mm*750mm

Combined Altitude Temperature and Humidity (CATH) test chamber

Combined Altitude Temperature and Humidity chamber can simulate pressure, temperature and humidity in its test space. It is primarily used in R&D and testing of aerospace components.

Features

STD: IEC 60068-2-x, MIL-STD-810
Specifications of the CATH chamber:
Temp: -70° C to 180° C
Humidity: 15-95% RH
Altitude: 1 Lakh feet ≈ 30 Km ≈ 10mbar pressure
High pressure: Up to 2 bar at ambient temp
Ramp rate: 7° C per min
Volume: 950 litres
Internal dimensions: 1000mm*980mm*950mm

Environmental chambers (32 CFT/64 CFT)

To perform the environmental tests like dry heat, cold, temp cycling, composite temp and humidity cycling tests for electronic products at component and sub systems level.

Features

STD: IEC 60068-2-x, MIL-STD-810
Specification of Environmental chamber:
Temp: -70° C to 180° C
Humidity: 10-98% RH
Ramp rate: 15° C per min in 32 CFT volume
chamber & 5° C per min in 64 CFT volume chamber
Internal dimensions:
32 CFT: 970mm*940mm*990mm
64 CFT: 1200mm*1170mm*1140mm

Data Loggers

Portable data loggers for monitoring temperature, voltage and current. It can have
30/60 channels which can be configured for monitoring and recording of required parameters

HALT & HASS

HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) for evaluating product reliability of all industries. Through HALT, the temperature and vibrations are raised for hostile testing for critical areas like aircraft. Through this testing, the simulation helps in eliminating any chance of failure.

This testing is being used by major manufacturing and R&D organisations to improve product reliability.

Features

STD:
Combined Temp and Vibration: -100 C to
+200 C with Ramp Rate of 70 deg/m
Vibration: 6 degree

* Awaiting Installation

Thermal Shock

Thermal Shock for exposing EUTS to sudden temperature changes in a very short time.

Features

STD: IEC 60068-2-x, MIL-STD-810
Cold zone: Ambient to -65° C
Hot zone: Ambient to +180° C
Volume of the chamber: 110 litres
Internal dimensions:430mm*630mm*530mm

Testo Thermography

With 160 x 120 pixels, your ideal entry into thermography, you can visualize temperature differences from 0.12 °C, and automatically recognize hot-cold spots.

Features

High resolution and image quality
Connection to App and other Testo measuring instruments
Automatic setting of emissivity
Objectively comparable images
