Overview

The calibration standards and regulations for bimetallic thermometers refer to the "National Metrology Calibration Regulations of the People's Republic of China JJG226-2001" published by China Metrology Press. The accuracy level and maximum allowable error (allowable error limit) of the thermometer should comply with the provisions of Table 1.

Product Details

1product overview

The bimetallic thermometer calibration device is developed by our company through years of research and process development. It is an important experimental equipment in temperature measurement calibration and is widely used for the calibration of thermal resistors, thermocouples, thermometers, including standard thermometers. It can also be used for experimental research in scientific research departments. It provides a stable and uniform temperature field for comparing standard and tested readings, thereby obtaining errors. It is filled with a heat transfer medium in a container with an insulation layer, controlled by a precision temperature controller, and fully stirred by a motor stirrer to achieve the goal of forming a uniform and stable temperature field.

3、 Product features:

1. The shell adopts carbon steel surface spraying technology, with beautiful color and scratch resistance; 
2. The controller panel adopts stainless steel wire drawing technology with chemically etched fonts, which has an elegant appearance and is sturdy and durable; 
3. The tank body and heating tube are made of all stainless steel, which is corrosion-resistant, has a long service life, and has a beautiful appearance; 
4. The temperature control device adopts a temperature controller specially designed for precision constant temperature baths; It has a unique anti saturation PID2 control law, supplemented by power supply voltage compensation regulation, and PID parameters do not require manual tuning.
5. The mixing device adopts a domestically produced special motor with a long shaft that directly drives the slurry. Compared with magnetic mixing, it has higher torque, sufficient mixing, uniform temperature field, no runaway, and less magnetic interference; 
6. By adopting advanced thermodynamic flow principles and scientific flow field design, fluid heat transfer is more complete and mixing is more uniform, thereby ensuring the uniformity of the temperature field in the constant temperature bath; 
7. By using a heating rod for heating, the heat transfer area is large and uniform, overcoming the disadvantages of local overheating caused by heating wires and coking of the working medium, the working life and insulation of the heater are improved.
