PROD-Mapping-Kit-1280x960 (1).jpg


Validation mapping kit

A reliable, easy-to-use alternative to thermocouple-based equipment, bulky data acquisition systems, and less robust data loggers. Ideal for stability chambers, refrigerators, freezers, incubators, warehouses, ambient environments and other demanding studies. The mapping kit comprises the vLog VL software, vLog's IQOQ, and Vaisala's data loggers including:

  • Temperature: -90 to 70 °C, up to 0.1 °C accuracy and 0.02 °C resolution

  • Relative Humidity: 10 to 90 % RH up to 1 % accuracy and 0.05 % resolution

  • Measurement accuracy specified for one year, eliminating the need for frequent calibration

For temperature and humidity qualification of GxP environments

For validation/mapping of GxP environments

The vLog system is the most accurate and effective solution for understanding your environments and complying with regulations. With easy set-up and placement of self- contained data loggers, you can be mapping a chamber in minutes.

For wide-range temperature monitoring​

Vaisala's multi-application temperature data loggers monitor temperatures in up to four applications with one logger – ultra-low temperature freezers, freezer/refrigerators and incubators. A superior alternative to chart recorders and hard-wired systems. The DL-series loggers connect to Vaisala's viewLinc software to provide historical and real-time data, remote alarming, and reporting in compliance with global regulations and standards. 


For monitoring temperature, relative humidity, current, voltage & door contacts

for Quick Inspections and Spot-Checking

The Vaisala HMT140 Wi-Fi data logger is designed for humidity, temperature and analog signal monitoring in cleanrooms, warehouses, freezers, laboratories, blood banks and other life science applications. This battery-powered device simplifies installation and eliminates the need for power or network cables. Combined with viewLinc monitoring software, the HMT140 ensures continuous historical and real-time data with reliable remote alarming.
