Benefits of Tetra vs. ISC LTX312...

The ISC LTX312 simultaneously monitors up to 3 gases; Tetra is a 4 gas unit with a variety of sensor combinations that interchange easily, allowing additional flexibility. Tetra comes standard with Ingress Protection to IP65.  This is an international classification system for the sealing effectiveness of enclosures of electrical equipment against intrusion of foreign bodies and moisture.  Tetra's IP65 rating means it is dust-tight and protected from water projected from a nozzle.  LTX312 offers no IP specification.

The LTX312's visual alarm consists of only red LED's (light emitting diodes) only while Tetra comes equipped with an eye catching red-blue flashing alarm.  Blue light photons have been proven to have higher energy than red, increasing user visibility and safety.  Some applications require red lights which is why Tetra incorporates red in its visual alarm.

When it comes to ease of use, Tetra features simple 1 button operation while LTX312 requires 2 buttons.  With a display on top, Tetra is easy to read with no need to handle the unit.  LTX312 has the display on the front of the instrument, making it more difficult to read in confined spaces.

LTX312 lasts only 9 hours on full charge using out of date Nicad battery technology.  Tetra performs continuously for 12 hours or more on full charge using Li-ion battery.


Unique Features of Tetra...

Tetra's rugged casing allows it to be dropped and float in water, saving on repairs and replacement costs.  Tetra is available with a built-in internal pump and is certified valid for use in temperatures up to 131F, making it suitable for use in foundries, steel mills and hot outdoor climates.  Tetra is provided with internal software that conforms to IEC 61508 standards, guaranteeing software quality and reliability.  LTX312 offers no such conformity.

Get the Most for Your Money...

Both the ISC LTX312 and Crowcon's Tetra are quality multi-gas portable gas detection instruments.  When purchasing a gas detector, don't you want the most value for your money?  Tetra offers more features, higher quality construction and reasonable pricing.  Protect yourself and your employees with Tetra reliability while enjoying savings on operation, repair and replacement costs.
