The temperature and humidity calibration chamber, also known as the temperature and humidity standard Chamber, is a professional measurement for testing or calibrating mechanical temperature and humidity meters, digital temperature and humidity meters, temperature and humidity sensors, and hair type and dry wet ball type temperature and humidity meters. The instrument can provide a uniform and constant temperature and humidity environment for the meter under test. With the precision dew point meter and precision digital thermometer as the standard device, the measurement work can be carried out.

Dearto currently has more than a dozen temperature and humidity calibration chamber with different styles, functions and prices.

At present,DTSL-1G Series temperature humidity chamber price is about $9,999-$15,000, and DTSL-2G Series the largecalibration chamber can be upgraded to an automatic verification system, and temperature and humidity calibration chamber price is is about 19,999-35,999 US dollars.

Regulations

The temperature and humidity calibration chamber mainly follows three regulations:

Among them, "J.TF 1564-2016" Calibration Specification for Temperature and Humidity Standard chamber" is used to evaluate the performance indicators of the temperature and humidity calibration chamber itself, and the traceability and certificate of the calibration chamber also follow this specification.

The other two regulations are:

"JJG 205-2005" Verification Regulations for Mechanical Thermo-Hygrometer" and

"JJF 1076-2020" Calibration Specifications for Digital Temperature and Humidity Meters"

These two procedures are the procedures followed by the daily work of the calibration chamber;

The fluctuation, uniformity and rate of change indicators of Taian Dearto calibration chamber are all better than the above three requirements.

Features

The temperature and humidity calibration chamber of Dearto is widely used in metrology institutes at all levels at home and abroad, pharmaceuticals, electric power and other industries. The reason why the calibration chamber is so popular with users is because it has four characteristics:

1.High precision and good index

The temperature fluctuation is better than ±o. 1C, and the uniformity is better than 0.3C;

The humidity fluctuation is better than ±0-8%RH, and the uniformity is better than 1%RH;

The temperature control of Dearto's calibration chamber adopts the "liquid bath constant temperature and other plate heating technology", which is Dearto's patented technology. The design of the lower chamber is equivalent to a precision constant liquid calibration bath. After the liquid medium in the constant calibration bath is controlled to the target temperature, it circulates around the measurement chamber, so the entire measurement chamber is almost immersed in the liquid, which is equivalent to a half-bath constant temperature bath. Heating by heat radiation. This principle ensures that the temperature in the measurement chamber is uniform and stable.

Its humidity control method is optimized and improved on the basis of the "shunting method humidity generation principle", and adopts ultrasonic atomization and ultra-low temperature condensation drying technology. This principle ensures the rapid stability of the calibration chamber. For example, at 20C, from 40%RH to 60%RH relative humidity, it only takes 15 minutes to achieve stability. In fact, the device itself only needs 5 minutes to stabilize. The reason why we claim 15 minutes is because it takes 10 minutes to test the volatility index. In this way, under the premise of ensuring the indicators, the work efficiency is greatly improved.

2. Excellent quality

The Dearto calibration chamber relies on the design to ensure the indicators, and relies on the materials and craftsmanship to ensure the product quality and life. The entire body of the verification box adopts steel plate pickling, phosphating, and plastic spraying processes, which is overall beautiful and corrosion-resistant;

It reserves three observation windows, and each observation window is made of five layers of vacuum glass. Customers can view and record the readings of the tested meter through the three observation windows. fog.

(3) Good security

This calibration chamber has all-round protection for the safety of use; it has low liquid level detection in the water tank, and can remind when the pure water in the water tank is insufficient. Features such as overheating protection, it is very safe to use.

(4) The design is humanized and highly intelligent

Dearto temperature and humidity calibration chamber, after long-term feedback from customers, metrology teachers have provided us with many practical and valuable suggestions, making our products more and more humanized and intelligent.

The calibration chamber is equipped with a 7-inch high-definition touch screen. All the settings and operations of the calibration chamber can be realized through the touch screen. In addition, we can also realize the remote operation and viewing of the calibration chamber through the mobile APP and computer software, which improves the quality of the test box. The work efficiency of metering personnel avoids repeatedly checking the equipment status in front of the equipment.

The calibration chamber is equipped with wifi, network port and RS-232 communication interface, which can read data and control through the communication port to realize the system integration of the calibration chamber.
