The Tº Sentry TT-150 and TT-200 are battery operated NIST-traceable, single probe temperature and humidity wireless Wi-Fi transmitters, covering -200 °C to +100 °C and 0% to 95% relative humidity, in various selectable ranges, housed in a free-standing or wall-mounted enclosure. The system includes high and low temperature alarms with audible and visual alarm indicators.
Features including temporary muting of the audible alarm for user-selectable periods up to 120 minutes; optional UL listed plug-in power supply; and optional dry contact input for refrigerator or freezer door monitoring, make the Tº Sentry TT-150 and TT-200 ideal for applications such as the remote monitoring of freezers, refrigerators, and walk-in environmental chambers.
The Tº Sentry TT-150 and TT-200 temperature and humidity transmitters are designed for wireless Wi-Fi communication to Hampshire Controls’ T? Sentry ALERT Monitoring System data logging software SQL database. Wi-Fi transmission is via a standard UDP/IP protocol every 3 minutes, so the data is also available to other logging systems upon request. Consult Hampshire Controls for available options and configurations.
