Rotronic Hygrolog HL-NT3 Humidity & Temperature Data Logger

Rotronic Hygrolog HL-NT3 is a version of the HL-NT data logger series with two additional external probe inputs for the measurement of humidity and temperature offering high precision and reliability.

Additional probes can be connected to the Hygrolog HL-NT3 data logger via a docking station.

The HygroLog HL-NT humidity, dew point and temperature data logger can be used with any of the HygroClip 2 probes. The HL-NT can monitor up to 7 probes as well as up to two external on/off contacts, such a a door contact.

Typical applications include clean rooms, storerooms, server rooms, production areas, residential and office rooms and shipping

ROTRONIC – HUMIDITY MEASUREMENT IN THE PHARMACEUTICAL INDUSTRY

The pharmaceutical industry is one of the largest users of humidity measurement equipment. Most drugs are sensitive to variations in humidity and moisture levels, so these need to be considered and controlled using measurement instruments, probes and sensors for the final products to be consistent in quality and performance.

Humidity Measurement Applications

Humidity instruments are used to both control (transmitters) and monitor (transmitters or data loggers) these conditions during “accelerated conditions” drug testing.

Production machines, driers, tableters, and coaters are all sensitive to humidity – quality control requires machine monitoring, area monitoring and final product Equilibrium Relative Humidity (ERH) measurement.

Clean room environments are humidity critical – environmental monitoring system (EMS) and measurement is validated to conform with regulatory requirements.
