The JK50 online multifunctional formaldehyde detector is used for 24-hour continuous online monitoring of concentration and temperature and humidity measurement of on-site multifunctional formaldehyde detectors. It can simultaneously detect 1-6 gas concentrations and temperature and humidity, display concentration and over limit sound and light alarms on site, and remotely transmit data. Using a 2.5-inch high-definition color screen to display concentration in real time, and selecting gas sensors based on electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoionization principle from current industry brands according to different detection gases, as well as high-precision capacitive digital temperature and humidity sensors from Switzerland, JK50 advanced circuit design, mature core algorithm processing, has obtained multiple software works and appearances, thus giving birth to the new generation of multifunctional fixed online formaldehyde gas detection alarm in the industry. JK50 can detect gas concentrations in pipelines, confined spaces, and atmospheric environments, as well as gas leaks and high concentrationsSingle gasThe purity. The sturdy and durable explosion-proof shell and fluorocarbon paint surface treatment process are suitable for various hazardous locations and corrosive environments with strong acids and alkalis. They are wear-resistant and can withstand paint peeling within 10 years.
Exceeding national standards, resistant to high-intensity pulse surge current impact. High reliability and stability.

The monitoring center, monitoring equipment, and monitoring computer can monitor the concentration on site in real-time through free upper computer software or gas alarm controllers.
● Compatible with various secondary meters, data acquisition modules, PLC, DCS systems, and can directly drive equipment such as solenoid valves, fans, alarms, etc
High power devices can be driven by driving intermediate relays. The optional JSA2000 controller can monitor 1000 detectors simultaneously.
● Large capacity data storage function, which can record real-time concentration values, temperature and humidity, or only record alarm values and time.
Supports local storage or SD card storage. The standard capacity for local storage is 100000 records, and larger capacity should be specified when ordering.
The storage capacity of SD card can be customized. Export and analyze data through free upper computer software, supporting on the local machine
Viewing or deleting data can be set to automatically overwrite or not overwrite data when the capacity is insufficient, and the recording function will automatically stop.
Equipped with an infrared remote control, it can be operated without opening the cover in dangerous situations, such as modifying alarm points, concentration calibration, zero calibration, noise reduction, etc
Factory reset, enter menu, view records, 4mA output, 20mA output (this function is required for calibrating other acquisition devices).
The interface is selectable in both Chinese and English, with a default Chinese interface that supports free switching of gas concentration units. Conventional gases do not require input of molecular weight, while special ones do
The molecular weight of the gas input is automatically calculated and switched, with units available: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L
The 2.5-inch high-definition color screen (LCM) displays real-time concentration, time, temperature, humidity, storage status, and other information, and can simultaneously detect 1-6 gas concentrations and temperature and humidity. The menu interface uses high-definition simulation icons to display the function names of each menu, and provides concise Chinese or English operation prompts.
Three display modes can be switched: simultaneous display of multiple gas concentrations, large font cyclic display of single channel gas concentration, real-time curve, and each channel
The automatic or manual cycle can be switched between, and whether to display the maximum value, minimum value, and gas name can be set. Historical record curve graphs can also be viewed.
