Rotronic Hygro Log HL-NT Humidity Temperature Data Logger
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. When used together with the validated ROTRONIC HW4 software the HygroLog HL-NT data logger complies with FDA 21 CFR part 11 regarding electronic data records and electronic signatures (ERES). The HW4 software can display the data from several data loggers on multiple PCs and can centrally record on one of the PCs the measurement data from several loggers. As a protection against power outages and network failures, HW4 can be used to automatically download the locally recorded data at regular intervals of time.
• Relative humidity, temperature, dew point or other calculated parameter
• Measuring range: 0 to 100%RH and -100..200°C /-148..392°F (with external probe)
• Interchangeable humidity-temperature HygroClip 2 probe for fast and easy maintenance
• Wide selection of probes to satisfy every application
• Optional internal probe, protected against unauthorized removal
• Large recording capacity (depends on the size of removable flash memory card)
• Power supply: A/C adapter, backed up by a standard or rechargeable 9 VDC battery
• Full featured, Windows based ROTRONIC HW4 networking software
• HW4 software has optional OPC tags to export data to any third-party OPC client application
