Recommendations for online dew point meters or online trace water analyzers

For domestic options, you can consider the dew point meters produced by Chengdu Instrument Factory~~

Xi’an Jueneng’s version should work too, right? . . .

The technical complexity of dew point meters isn’t very high~~ it mainly comes down to cost-performance~~

Our company purchased four sets of dew point meters; it’s okay, they’re not too expensive

We are from Xi’an Shiding; we have been manufacturing dew point meters and similar products for many years. It is a joint-venture brand that is widely used in the chlor-alkali, polysilicon, and coal chemical industries. You can get in touch. If it’s convenient for the poster, please leave your contact info to give it a try. My email address is scly8844@163.com, and my phone number is 13880837230

Our company has purchased four dew point meters. They’re okay; they’re not too expensive. Is it possible to find out what brand they are? Thank you all for your guidance!

We use GE products from the United States; when they break down, it’s very troublesome to repair them and it’s also expensive. We’d like to use a product made in China or one that is widely used by others, preferably one for which there are repair services available in China

We have gas moisture meters that can measure the ppm level of trace water in highly corrosive gases such as chlorine/hydrogen chloride in real time; the sensors are intrinsically safe and explosion-proof, and they can also detect trace water in hydrocarbon gases.

It provides displays for temperature, humidity, and dew point, along with various graphical representations. ● The sensor is treated to resist corrosion. ● It outputs 4-20MA signals as well as via RS232/485 interfaces. ● It has a USB port for data recording (optional). ● It can measure dew point, temperature, and humidity. ● A pressure sensor can be added as an option to measure pressure as well. ● This corrosion-resistant dew point transmitter is suitable for use in the lithium battery industry. ● Its excellent stability helps to save on calibration costs. ● The dew point measurement range is from -60 to +60 °C. ● It features a fast response time. ● It can withstand pressures of up to 20 bar. The FM850 dew point transmitter, with its corrosion-resistant technology, is highly suitable for industrial OEM applications such as air drying equipment and plastic drying equipment. Power SF6, lithium battery manufacturers – thanks to their compact structure and excellent stability, they can even be used in the smallest drying devices. The design concept of the FM850 online dew point meter is to enable simple and reliable continuous measurement of the dew point of air and gases. A compact panel-mounted or desktop display unit is connected to the dew point meter, while the sensor is fixedly installed at the plant site or process control location. The structural design of the FM850 online humidity meter is highly sophisticated; it features a standard panel-mounted format (168 x 96 mm), allowing it to be easily installed on any control panel. The alarm setting buttons are located on the front panel, which has an IP54 protection rating, while the sensor has an IP65 rating. ■ Users can choose the type and range of the output signal. ■ It supports measurement of humidity, temperature, and dew point (a pressure sensor can be added as an option for pressure display). ■ All three parameters can be displayed in graphical form. ■ It offers 4-20mA/0-10V analog outputs as well as RS485 communication capabilities. ■ It displays dew point, PPM, temperature, and humidity simultaneously. ■ It includes alarm indicators and multi-variable relay control functions. ■ The humidity sensor includes self-checking and drift compensation functions. ■ Temperature and humidity can be calibrated and adjusted. ■ It has a recording function. ■ The humidity sensor also features self-checking and drift compensation functions. 1) It has a disconnect protection function. Description of the functional modules of the FM850 dew point tester/FM850 transmitter: The functional modules of the FM850 can be purchased separately; they include the analog output module, the communication module, and the relay control module. The analog output provided by the FM850 is either a 4…20mA current signal with three wires and a common ground, or a 0…10V voltage signal. Users can achieve a conversion from 4…20mA to 0…10V using jumpers; the analog output signal can be used for remote transmission, recording, control, or data processing. Each analog output can be set to either temperature, humidity, or dew point. The FM850 comes standard with two relay contact signal outputs, which can be used to trigger actions based on the upper and lower limits of temperature, humidity, and dew point, switching from an open state to a closed state. Technical specifications: Dew point range: -60~60°C Td (other ranges available upon request). Humidity range: 0~100% RH, displayed in PPM. Temperature range: -40~85°C (optional: -50~200°C). Accuracy: ±2°C Td, ±0.8% RH, ±0.2°C. Output: 4...20mA, 0—10V, RS232/485. LCD display: Temperature in °C, relative humidity in %RH, dew point in °C Td, PPM. Power supply and load: 24-220VDC/AC; voltage output >1000 ohms, current output
