Main features

Intelligent programming function

With multi-segment programming function, common temperature humidity calibration points can be programmed into the verification box in advance, and can be started with one key (timed start), which is automatically executed in sequence; there is no need to repeatedly set the temperature humidity points every time.

Mobile phone control function (WiFi control)

Equipped with mobile phone APP software, you can remotely control the temperature humidity verification through the mobile phone; read the current temperature and humidity values and the running status of the verification box in real time;

PC remote function (network port / WiFi / serial port)

Equipped with computer software (optional), you can remotely control the temperature and humidity verification through the computer; read the current temperature and humidity values and the running status of the test box in real time; you can set the temperature and humidity values remotely; start and stop the temperature and humidity test box remotely; the measurement teacher does not need to stare Check the box, check the status; in the process of stabilizing the check box, you can also do other work. You only need to look at the computer screen remotely, liberating the measurement staff and improving the efficiency of the measurement work.

Volatility automatic calculation

1. With automatic real-time calculation of fluctuation degree, it can automatically calculate the fluctuation of the current temperature and humidity of the temperature humidity calibration chamber, determine whether the verification box is stable, and can start the measurement and calibration work.
2. The fluctuation calculation period can be set freely (1min, 5min, 10min, 20min, 30min), in accordance with the usage habits of different measurement teachers, and the stability of the test box can be judged according to different periods.

Stability tips

With intelligent stability prompt function, you can automatically judge whether the test box is stable according to the parameters such as temperature and humidity deviation, fluctuation, and stability time of the test box. After stabilization, a green prompt "temperature and humidity has stabilized" appears on the screen as a reference for the measurement teacher to start reading To improve the efficiency of verification.。

Maintenance function

The verification box will perform automatic anti-rust maintenance on the internal proportional valves, atomizers and other parts of the equipment according to the internal logic to reach the maintenance cycle and spare parts replacement cycle.

Curve zoom function (save curve)

Touch screen, support multi-touch, you can use two fingers to drag and zoom to view partial and overall curve details (same way as mobile phone zoom picture); curve supports one-click screenshot, save curve data into picture format, as maintenance,data process records.

Segmented PID control

The temperature is controlled by multi-stage PID, and the temperature control effect is better (small overshoot, rapid adjustment, and small fluctuation), and the humidity is controlled by multi-stage PID, which has good control effect.

Data logging / export (USB)

Insert the U disk, you can automatically record the operating data of the verification box, temperature and humidity curve data, form an EXCEL table, and export to the U disk with one click.

Curve display

High speed sampling smooth curve

Multiple protection

Compressor start-stop, overheat protection (over-temperature protection), anti-drying protection, low liquid level reminder to add water reminder, automatic fluid replenishment can have multiple protection functions

Multi-point correction

Wide range of correction points, smaller deviation and good linearity

Equipped with frequency conversion fan, regular start-up function, and can be upgraded to an automatic temperature humidity verification system.
