INFICON Introduces D-TEK Stratus Refrigerant Leak Detector

D-TEK Stratus combines the field-proven leak detection reliability of INFICON’s D-TEK Select with the cloud hunting capability of a large portable monitor to help find leaks faster. With cloud hunting mode, the large, easy-to read LCD display with ppm readout helps the operator to find the area highest in concentration and then easily switch to pinpoint mode to quickly find the leak. D-TEK Stratus has a sensitivity of 0.03 oz./year (1g/year) and this sensitivity will not degrade over time.

To minimize maintenance, the all new, redesigned infrared sensor offers the longest sensor life in the industry. Easy field replacement of the sensor keeps the technicians working virtually uninterrupted. Additionally, the lithium ion battery is quick to charge and is also easily replaced in the field, when necessary. This revolutionary instrument has a variety of robust features, including automatic and manual zero modes and the ability to detect all CFCs, HCFCs, HFCs and HFOs, blends (including A2Ls), and CO2
(requires optional CO2 sensor. D-TEK Stratus comes in a rugged carrying case and has a two-year replacement warranty.
