Product introduction
JT2022 is a hand-held portable WBGT index meter. The professional industrial design structure appearance ensures the overall high quality of the product. The sensors can be disassembled independently, and the copper black ball with a diameter of 50mm is used to further improve the overall portability of the instrument. The sensor connection uses aviation connectors, which are firm and stable and not easy to shake. The instrument screen uses an LED display with backlight, which is user-friendly and easy to read It can display WBGTin, WBGTout value, Ta, Tg, Tnw, RH, and WBGT measurement curve.
The instrument has a built-in lithium battery, which can be used continuously for more than 96 hours when fully charged. There is a standard 1/4-inch tripod interface on the back of the instrument, which can be connected to a tripod for measurement.
According to standards
GB/T 4200-2008 Classification of High Temperature Operations
GBZ/T 189.7-2007 Measurement of Physical Factors in the Workplace - Part 7: High Temperature
GB/T17244-1998 Evaluation of Staff Thermal Load in Thermal Environment Based on WGBT Index (Wet Bulb Black Bulb Temperature)
ISO 7243-1989 Evaluation of thermal load on operators based on the WBGT index (wet bulb black bulb temperature) in thermal environments
50mm black ball diameter, handheld host, easy to carry
Built in humidity sensor, displaying relative humidity at the same time
Real time measurement curve display, intuitive viewing of WBGT change trend
Built in high capacity memory card, capable of recording massive measurement data
The built-in lithium battery has a standby time of up to 9 days (screen off state)
There is a 1/4-inch tripod interface on the back of JT2022, which can be installed on a tripod to achieve fixed measurement. The large-capacity lithium battery can ensure continuous measurement for more than 9 days. The 16GB memory card allows users to use smaller recording intervals and measure for a long time.
Built-in large-capacity lithium battery
- fully charged state can be used continuously for more than 9 days (screen backlight off state)
standard 16GB large-capacity data storage card
- long-term measurement without worrying about storage space.
A maximum delay of 60 minutes can be set for recording
—that is, the instrument will start recording data according to the set delay time (need to be turned on)
JT2022 adopts LED color screen
WBGT measurement results are highlighted and easy to read.
Humanized human-computer interaction interface.
The operability options and status indication area are set at the bottom of the screen, so that you can know the current settings and measurement information at any time.
