Overview:
DTHTH high temperature and high humidity smart calibration chamber can be used for temperature and humidity sensors, digital temperature and humidity meter, mechanical temperature and humidity meter and other temperature and humidity instrumentation calibration calibration and testing work.
Product Features
High-definition touch screen: high-resolution capacitive screen, display clearer, 3-point touch support, in line with the customer's mobile phone touch operating habits.
Wifi control: mobile phone / pad remote setting temperature and humidity, enjoy the device, read the current temperature and humidity values and fluctuations in the state of the device.
State prompts: temperature and humidity fluctuations in real-time calculation display, to reach a stable state prompts U disk insertion detection, wif connection prompts
Curve display: temperature and humidity curve real-time display, support touch zoom panning operation, a key screenshot to save the curve to the U-disc
Data logging: temperature and humidity data is automatically saved in xls format, one key to export to U disk.
Timed power on: the system has a timed power on function, which can be realised before going to work, the equipment is timed to start working immediately after going to work, without waiting.
Multi-point calibration: support for temperature and humidity sensing the most multi-point calibration, the temperature sensor value can be segmented multi-point correction, to ensure that and the standard to be consistent.
Segmented control: temperature and humidity are using segmented PID control programme fast and stable ‘zero’ overshoot, rapid stabilisation of humidity from 40% RH to 60% RH in just 15 Minutes fan speed: the main circulating fan in the inner chamber, using variable frequency speed control, through the touch screen, set the fan speed
Multi-protection alarm: thermostatic tank overheating protection, liquid level alarm; replenishment tank water shortage reminder; compressor overheating alarm, start-stop protection function
Communication expansion: with network port, wifi interface, USB interface, RS-232 interface, can communicate with PC, data reading, system settings.
Temperature range: -40℃ ~ 180℃
Humidity range: 10%RH ~ 95%RH
85% @85℃ & 95% @95℃ are optional.
