Description
Overview
GAOTek handheld gas detector with the most advance nanometre semiconductor technology, ultra-low power 32-bit microprocessor,24bit ADC data acquisition chip, outstanding accuracy.3.5 inches IPS technical grade display with a pixel up to 320 x 480, display technical indicators and gas concentration value perfectly. Three concentration units are available PPM, %VOL, mg/m3. Users can combine different sensors,1 to 5 kinds of gas can be detected at the same time, PM 2.5 dust sensor, temperature and humidity sensor, and other kinds of sensors are available. Up to 100,000 group data can be stored, the user can view history data on the display, and data output is available. A Z 1000 allows the user to connect to a portable printer to print data. With temperature and humidity detection, the user can detect temperature and humidity values on the scene or the temperature and humidity value inside the pipe. Five operation modes are optional: Detection mode, Storage mode, Printing mode, Display mode, Pumping mode. With high-power pump allows the device to work under a tiny negative pressure condition, and the reasonable gas chamber design ensures that the sensor is not affected by the pressure. With over-voltage protection, overcharge protection, electrostatic prevention, and magnetic-field interference prevention. All software automatic calibration, sensor up to 6 levels target calibration, ensure the accuracy and linearity of the entire measurement, also with data recovery function. Chinese and English operation models are available, and user-friendly. With temperature and humidity compensating function. With dust filter and dust-proof design allow the device applied in all sorts of harsh conditions.
