The Winland Temp-H-S is a high-temperature-range sensor accessory built with a stainless-steel thermistor housing rather than Winland's waterproof-sealed version, covering the same 32 to 221 degree Fahrenheit range used across Winland's high-temperature sensor line. Like the rest of Winland's Temp-series probes, it's built to extend the EnviroAlert Professional Gateway, EAPro Wireless Multi-Function Transmitter, and EnviroAlert 200/400 series monitors with elevated-temperature sensing, over a cable run of up to 1,000 feet on appropriate twisted-pair wiring. The stainless housing suits harsh or physically demanding mounting locations rather than submersion, where Winland's waterproof Temp-H-W is the better fit.
