详细内容
背光液晶显示在大的数字和符号的信息来避免语言沟通不畅。屏幕显示和报警功能的不断集中注意。峰浓度,平均浓度(TWA值),和短期暴露限(STEL)可以显示与触摸个按钮。高性能,耐冲击,微型XXS传感器快速反应由于快速的电化学反应时间短的扩散路径。在短短的10秒进行冲击试验。从顶部和前监测气体的访问(如果个传感器意外覆盖)提供增加的性。入口是由灰尘和水过滤器的保护。Backlit LCD shows information in large numerals and symbols to avoid language miscommunication. Screen displays concentration with notice and warning functions continuously. Peak concentration, average concentration (TWA value), and short term exposure limit (STEL) may be displayed with the touch of a button. High-performance, shock-proof, miniature XXS sensors react rapidly due to fast electrochemical reaction times and short diffusion path. Perform bump tests in as little as 10 seconds. Gas access from both top and front of monitors (in case one sensor is accidentally covered) provides increased reliability. Inlets are protected by dust and water filters.
When harmful levels of gas are detected, an audible multi-tone alarm sounds along with a visual 180° alarm and a built-in vibration alarm. TWA and STEL alarms are adjustable. Monitors may be programmed to remind user to run bump tests at set intervals. Feature fresh air and span calibration, adjustable operating time, concentration and event logger that shows date and time, and password protection.
Detectors are housed in impact- and chemical-resistant, RFI-shielding, rubber-coated polyamide for rugged use and are specially optimized for protection from electromagnetic effects. Stainless steel adjustable crocodile clip keeps monitor securely fastened to clothing. Sensors and batteries (included) are replaced easily.
Detectors can be equipped with an optional infrared interface and PC-connecting cradle. Pac Vision software configures all functions and calibrates and downloads stored data.
