Monnit ALTA® Wireless Thermocouple Sensors leverage Monnit’s award-winning remote monitoring platform to remotely monitor high-temperature applications, such as commercial ovens, kilns, and chimneys. Users benefit from a wireless data transmission range of 1,200+ ft, bank-grade security, and a temperature range of up to 400°C (752°F).

Monnit’s thermocouple is user-programmed to sleep for a specified interval, awake, capture analog data, and then convert this measurement into a temperature. If the sensor captures temperatures outside of user-specified thresholds, an alert is sent via text, email, or call. Monnit’s hardwired thermocouples feature a needle-style probe at the end of a 6’ lead (a K-Type Quick Connect Thermocouple is also available).

Anritsu MW series probes are ideal for measuring the temperatures at the surface of moving wires. Specific components may be combined to customize products for the needs of a customer's specific application.
