HTDF Humidity Temperature Data Logger

- Dual function data logger. - Toggle display between humidity and temperature. - Visual LED shows if limits are exceeded. - User Manual - Certificate of conformity Note: When ordering loggers, it is necessary to order at least one ThermaData® logger holder. The HTDF Humidity Logger is a data logger that measures and records both relative humidity and temperature over a range of -20 to 85°C and 0 to 100% RH. At programmable intervals, the HTDF humidity logger will simultaneously record temperature and humidity, logging up to a maximum of 16,000 readings (8000 humidity and 8000 temperature). The ThermaData HTDF Humidity Logger has an integrated LCD screen that displays temperature and humidity levels and includes internal humidity and temperature sensors. A UKAS 3-point humidity calibration certificate (25, 50 and 75% RH) is available as an option at a preferential price when purchased with these thermo-hygrometers. Each humidity logger includes a red and green LED, flashing green LED indicates the logger is active/logging and flashing red LED indicates your custom preset alarms have been exceeded. ThermaData loggers are suitable for a wide range of applications including HVAC climate monitoring, quality control or storage areas and many more Range - temperature: -20 to 85°C Range - humidity: 0 to 100% RH Resolution - temperature: 0.1°C Resolution - humidity: 0.1% RH Accuracy - Temperature: ±0.5°C (0 to +45°C), ±1°C (-20 to +70°C), ±1.5°C (+70 to +85°C) Accuracy - humidity: ± 3% RH @ + 25°C (10 to 90% RH) Hysteresis - humidity: ± 1% RH Memory: 2 x 8000 conferences Sampling rate: 6 seconds to 255 minutes Battery: 3.6 volt half AA lithium Autonomy: 2 years minimum Sensor type: temperature: silicone bandgap - humidity: capacitive polymer Display: 10mm LED toggles every 6 seconds / 2 LEDs Size: 76 x 23mm Weight: 80 grams Housing material: ABS plastic with Biomaster antibacterial additive Water / dust resistance: water resistant Measurement scale: Celsius / Fahrenheit &% rh OS: Windows
