Vaisala Wi-Fi Data Logger HMT140 is designed for humidity, temperature, and analog signal monitoring in warehouses, freezer and cryogenic farms, laboratories, blood banks, and many other applications.

Performance

HMT140 incorporates Vaisala HUMICAP technology to measure relative humidity and temperature accurately and reliably. The HUMICAP sensor is resistant to dust and most chemicals. Alternatively, HMT140 can connect to Resistance Temperature Detectors (RTDs) or Voltage, Current, and Door Contact sensors, making HMT140 an extremely versatile Wi-Fi data logger. Combining RTD and contact inputs, HMT140 is ideal for monitoring chamber/door contact excursions. Using Wi-Fi connectivity, HMT140 can connect through any wireless access point. The battery-powered logger can operate for 18 months continuously. The optional local display allows HMT140 to indicate process parameter values and any limit warnings. The LCD display is operated using a power-saving infrared sensor that is motion-activated. When activated, the display indicates the current measurements. All data is logged locally and uploaded to the Vaisala viewLinc monitoring system software at preset intervals and during any parameter excursions. Autonomous operation with audible and visual alarming (beep and flashing LED) ensures that local alerts are indicated independent of active network or server connection. The data logger’s enclosure is optimized for use in cleanrooms with a surface that is easy to clean and tolerates purifying agents.

Interchangeable Probe

HMT140 data logger uses an easily replaceable relative humidity and temperature probe. This allows for a quick recalibration of the data logger. The probe can be adjusted using one of Vaisala’s portable meters as a reference.

Available Options

The HMT140 data logger is available as wall-mounted or with remote probes. For extreme temperature applications or where space is limited, the remote probe is ideal.
