Formaldehyde gas is not only an intermediate in industrial processes, but also a potential pollutant in the home environment. Formaldehyde gas detector, the range mainly includes low concentration of formaldehyde in indoor environment control (0~ 2ppm) and high concentration of formaldehyde in industrial process (2~ 100ppm). Formaldehyde gas is easy to adsorb, poor stability, difficult to save, calibrating formaldehyde gas detector, often use standard devices now occurring formaldehyde standard gas.

The system generates the flow rate traceable to the SI units length and time. The pistons are moved via spindle of a stepper motor. In the initial state one of the piston is fully turned in and the other fully extended. Using the piston cross-section and the process speed the flow can be adjusted with high precision. At the end of the calibration process both pistons are in the opposite position to the initial position. The calibration device is preferably operated with air, on request for gases. The measurement time is greater than 25 seconds.

VAC capillary viscometer automatic calibration device, based on computer image processing algorithm, using automation and intelligent application technology, to achieve automatic calibration of capillary viscometer. The calibrated viscometer includes four categories: Ubbelohde Viscometer,Pinkevitch Viscometer, Cannon-Fenske Routine Viscometer ,Cannon-Fenske Opaque Viscometer. Calibration, each station can be placed in different types, different models of capillary viscometers, calibration process is independent of each other, can be asynchronous calibration, do not affect each other.

Volumetric bottles, cups, cylinders, pipettes, burettes are common glass gauges in the production and experiment process. In order to ensure the accuracy and reliability of the measuring value, it is necessary to calibrate each glass measuring device, which is a daily measuring work with a large amount and a wide range. When measuring institutions check glass gauges, there are often many quantities, low charges, time consuming, fragile gauges and so on.

In line with FTM 3410, FTM 3450 standards, it is an important equipment for the development of MILPRF-7808, MIL-PRF-23699, SAR 5780 and other aviation lubricants. It can also be used as high temperature and high speed torque testing machine for lubricating oil, bearing life simulation testing machine, axial anti-alternating stress fatigue testing machine and so on. 

The LNI Schmidlin SA High Purity Nitrogen generators (HP-N2) produce laboratory high grade nitrogen for most of the laboratory applications and equipments. Designed with safety and convenience in mind, this system generates purified nitrogen, eliminating the need for inconvenient cumbersome high-pressure gas cylinders. The HP-N2 removes oxygen from air to less than 10 ppm (HC polluants to less than 0.1ppm if the option is installed). The typical flows are 500 ml/min, 750 ml/min, 1300 ml/min and 4000 ml/min. Includes smart compressor management.

The Mistral LCMS Evolution (PSA technology) include an integral oil-free air compressor and deliver a continuous stream of pure nitrogen gas of 98.5% with a flow rate of 35 Nl/min. It use the pressure swing adsorption (PSA) system that removes oxygen, carbon dioxide and water from compressed air. The resulting stream pure nitrogen is ideal for laboratory applications like LCMS techniques and other inert gas applications.

The spark test apparatus serves for testing intrinsically safe circuits. The test is based on whether the tested equipment is capable ofproducing sparks, arcs in normal operation, capable of igniting the gas mixture specified by the standard, in the given chamber, under given conditions. The apparatus includes a built-in gas mixer producing the gas mixture for testing and calibration with a high accuracy. The actualmeasuring process is completed with the purging of the chamber after the measuring process, aiming at the removal of the needless combustions products.

The MESG apparatus is capable of determining the g0 value (maximum experimental safe gap) and the associated g100 valuerequired for the classification of gases, vapours and mists. Furthermore the apparatus can be applied to check the accuracy of a given gas concentration. In order to attain the required accuracy, a stepping motor with gear transmission adjusts the gap size. During 80 steps the stepping motor makes 1 m. Thus the gap size can be adjusted with an accuracy of ± 1 m. The actual measuring process is completed with the purging of the chamber after the measurement, aiming at the removal of the needless combustions products.
