Introduction

DTLH-18BG Type Intelligent Temperature Humidity Calibration Chamber(-8℃~65℃) is used to detect digital temperature humidity meter, temperature humidity sensor, temperature humidity transmitter, temperature humidity inspection instrument, temperature humidity recording instrument, temperature humidity storage and other principles of temperature humidity meter calibration special verification equipment. The equipment is accurately measured by temperature humidity sensor and controlled by industrial programmable controller, which can realize automatic adjustment of humidity in humidity verification box. With high control and test accuracy, can provide continuous, repeatable humidity measurement, suitable for scientific research and product testing fields.

Execution verification regulation

“JJF1076-2020 digital thermohygrometer calibration specification”“JJG205-2005 mechanical thermohygrometer verification regulation”“JJF1564-2016 temperature humidity calibration Chamber specification”

Temperature Humidity calibration Chamber

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 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.
