Introduction

DTSL-Temperature Humidity Calibration Chamber(standard Chamber) is a special verification device for detecting hair temperature humidity meter(gauge) , wet and dry bulb thermometers, digital temperature humidity meter, and other various types of temperature humidity sensor. The equipment is accurately measured by a temperature humidity sensor and controlled by an industrial programmable controller, which can automatically adjust the humidity in the temperature humidity Calibration chamber. With high control and test accuracy, it can provide continuous and repeatable humidity measurement, suitable for scientific research and product testing.

Product function

HD touch screen:Using high-resolution capacitive screen, the display is clearer, multi-touch support, in line with customer mobile phone touch operation habits.

Wifi control:Mobile phone / pad remotely set the temperature humidity, start and stop the device, read the current temperature humidity values and fluctuations and other device status.

Status prompt:Real-time calculation and display of temperature humidity fluctuations, prompt to reach a stable state, U disk insertion detection, wifi connection prompt.

Curve display:Real-time display of temperature humidity curve, support touch zoom and pan operation, one-key screenshot to save the curve to U disk.

Data record:The temperature humidity data are automatically saved in xls format and exported to a USB flash drive with one click.

Timed start:The system has the function of timing start-up, which can realize the equipment start-up before work, and start working immediately after work without waiting.

Multi-point calibration:Supports multi-point calibration of temperature humidity sensors, and can perform multi-point corrections on temperature sensor indications to ensure consistency with the standard.

Segment control:The temperature and humidity are controlled by a segmented PID, which is fast and stable, and "zero" overshoot. The rapid and stable humidity rise from 40% RH to 60% RH takes only 15 minutes.

Fan speed regulation:The main circulation fan of the inner cavity adopts frequency conversion speed control, and the fan speed can be set through the touch screen.

Multiple protection alarm:Constant temperature tank overheating protection, liquid level alarm; reminder of water shortage in replenishing tank; compressor overheating alarm, start-stop protection function.

Communication extension:Equipped with network port, wifi interface, USB interface, RS-232 interface, can communicate with PC to realize data reading and system setting.

Product advantages:

Excellent technology

Humidity control adopts the shunt method humidity generation principle. Compared with the dual temperature method humidity generation principle, the time required for stability is greatly shortened and the verification efficiency is improved.

Temperature control adopts liquid bath constant temperature and isothermal plate heating technology, liquid medium heat radiation, the temperature is more constant, and the temperature field is more uniform.

The unique air circuit circulation design inside the measurement cavity ensures that there is no dead angle air flow; the frequency conversion technology is used to adjust the speed of the fan to ensure that the internal temperature field is even at low speed;

Product intelligence

Integration of measurement technology and internet of things technology, wifi remote control, make measurement easier.

High-definition touch screen control, multi-touch, greatly improve the user experience.

One-key start, fully automatic control, shorten the training period of measurement personnel.

Timing switch machine, remote switch machine, save time and improve verification efficiency.

Excellent quality

The outer shell adopts thick plate phosphating, passivation, spray plastic, anti-corrosion, anti-rust, salt spray resistance.

○ Can be upgraded to an automatic verification system

With the combination of intelligent image acquisition robot, dew point meter and industrial control computer, it can be upgraded to an automatic verification system of intelligent temperature humidity meter, which realizes the verification process automation, automatic record saving and report generation. It frees the measurement personnel from the reading and recording of the temperature humidity meter, greatly improving the verification efficiency and reducing the labor cost.

Main features

Intelligent programming function

With multi-segment programming function, common temperature humidity calibration points can be programmed into the verification chamber 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 Calibration through the mobile phone; read the current temperature humidity values and the running status of the verification chamber in real time; you can set the temperature humidity values remotely; remotely start and stop the temperature humidity verification chamber; 

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

Equipped with computer software (optional), you can remotely control the temperature humidity verification through the computer; read the current temperature humidity values and the running status of the test chamber in real time and improving the efficiency of the measurement work.

Volatility automatic calculation

With automatic real-time calculation function of fluctuation, it can automatically calculate the fluctuation of current temperature humidity of the temperature and humidity test chamber; the calculation period of the fluctuation degree can be set freely (1min, 5min , 10min, 20min, 30min).

Stability tips

With intelligent stability prompt function, you can automatically judge whether the test chamber is stable according to the parameters such as temperature humidity deviation, fluctuation, and stability time of the test chamber. 

Maintenance function

The verification chamber 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)

Capacitive touch screen, support multi-touch, you can drag and zoom with two fingers 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) The humidity is controlled by multi-stage PID, and the control effect is good.

Data logging / export (USB)

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

Curve display
