Proven Heated Diode Technology in an Affordable Package TEK-Mate is the ideal refrigerant leak detector for the light-to-medium duty user who demands reliable leak detection at a budget-friendly price. Features such as the patented INFICON heated diode sensor, variable intensity audible and visual alarms and automatic compensation for changing background refrigerant concentrations make TEK-Mate the best bargain in refrigerant leak detectors. See for yourself why TEK-Mate is the #1 selling refrigerant leak detector in the HVAC/R market.

Accurate and reliable readings for years to come The Wey-TEK Refrigerant Charging Scale truly is Laboratory Accurate and Toolbox Tough. Simple operation, outstanding durability, and great accuracy make Wey-TEK a great choice for any technician. A large weighing platform, 220 lb. (110 kg) capacity, and competitive price make Wey-TEK a great value. See why Wey-TEK is the most requested refrigerant scale on the market.

Provides Consistent, Accurate Responses to Next Generation Refrigerant As the first accurate, reliable, highly sensitive, cordless refrigerant leak detector, the original D-TEK revolutionized the field. Now we have built on that technology leadership with the D-TEK CO2, the only hand-held refrigerant leak detector designed especially to detect carbon dioxide, the next generation refrigerant. The D-TEK CO2 uses an innovative infrared absorption sensing cell which is extremely selective to carbon dioxide, yet its circuitry allows the instrument to equalize to the CO2 present in the atmosphere, so there is minimal risk of false alarms. D-TEK CO2 maintains its sensitivity over time for consistent, accurate and reliable performance. Its specialized infrared sensor cell lasts for approximately 1,000 hours, so you buy fewer replacement parts. Additional features include a charging status indicator, sensor failure indication, sensor test mode and rechargeable NiMH (nickel metal...

Innovative Infrared Technology Delivers Enhanced Sensitivity and Long Life As the first accurate, reliable, highly sensitive, cordless refrigerant leak detector, the original D-TEK revolutionized the field. Now we have built on that technology leadership to create D-TEK Select Refrigerant Leak Detector. This next-generation refrigerant leak detector uses an innovative infrared absorption sensing cell that is extremely sensitive to all refrigerants—and only refrigerants. D-TEK Select Refrigerant Leak Detector maintains that sensitivity over time for consistent, accurate and reliable performance, even with the newer refrigerant blends. Best of all, the sensing cell lasts for approximately 1,000 hours—almost 10 times longer than the original D-TEK sensor—to lower your cost of ownership and improve job site productivity. Additional enhancements include a charging status indicator, sensor failure indication, and rechargeable NiMH (nickel metal hydride) batteries. All in an...

WIRELESS FREEDOM MEETS SUPERIOR DURABILITY Building on the proven performance of Wey-TEK, the Wey-TEK HD Wireless Refrigerant Charging Scale sets a new standard for versatility, durability and accuracy in a 250 lb. capacity scale. Wey-TEK HD Wireless uses Bluetooth ® wireless technology to reliably display real-time measurements on your smartphone or tablet using the free app (on the App Store℠ or on Google Play™)*. If you prefer a dedicated handpiece, an optional wireless handpiece is available with a full color display. The app and handpiece both feature an innovative alarm mode which alarms when approaching a programmed target refrigerant charge amount, then alarms again when the target charge is reached. This allows you to walk away and multitask on the job site. Recent changes to EPA standards require logging of refrigerant. The Wey-TEK HD app includes a convenient job log feature to quickly and easily save and email spreadsheets for refrigerant tracking. For customers...
