GAOTek Testing Machine Leak Concentrator Portable Gas Analyzer – Multiple Alarm Mode

Description

Features

• It can detect 1 to 5 kinds of gases at the same time, and the unit can be switched:
  Optional units: PPM, mg / m3, VOL %, LEL %, PPHM, ppb, mg / L
• Built-in pumping measurement, integrated water vapor and dust filter, quick response, support long-distance sampling, built-in water vapor and dust filter to prevent damage to sensors and instruments due to water vapor and dust, can be used in high humidity, high dust environment.
• The sampling distance is larger than 10 m, and the special gas circuit design can be directly detected; negative pressure or positive pressure -0.5 to 2 kg of gas has no effect on the measurement result.
• The 2.5-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power, charging status, concentration unit, gas molecular formula, gas name and other information; the menu interface uses high-definition simulation graphics to display the function names of each menu.
• Large-capacity data storage function, support multiple storage methods
  Standard 100,000 data storage capacity, larger capacity can be customized; support real-time storage, timing storage, or only save alarm concentration data;
• Support this machine to view and delete data, you can also upload the data to the computer through the USB or RS232 interface and use the upper computer software to analyze the data and store and print.
• Optional high-temperature sampling and cooling filter handle or high-temperature and high-humidity pre-treatment system can detect
  flue gas with a temperature of 800 degrees. Higher temperature gas detection can be customized.
• Three display modes can be switched. Concentrations of 1 to 5 gases are displayed at the same time, the concentration of single-channel gas is displayed circularly in large font, and real-time curve display.
• Reflect the trend of gas concentration changes over a period of time in the form of a curve. You can choose to recover partly or completely to avoid worries caused by mis-operation.
• Can set to display the maximum, minimum, and average values
• Standard USB charging, with charging protection function, support USB plug
  It can be charged by a computer or a power bank, compatible with mobile phone chargers It has overcharge, over-discharge, over-voltage, short circuit, and overheat protection 5-level accurate power display. The detector can work normally when charging.
• Using 5500 mAh large-capacity rechargeable polymer battery, which can work continuously for a long time.
• High precision temperature and humidity measurement (optional).
• Support real-time detection or timing detection
• The pump can be turned off when not testing to extend the start-up time.
• Multiple alarm methods, multi-directional three-dimensional indication of alarm status when alarming
• Including sound and light alarm, vibration alarm, visual alarm on the display screen.
• The alarm types include concentration alarm, under-voltage alarm, and fault alarm.
• Multiple alarm mode settings: Low alarm, high alarm, interval alarm, weighted average alarm.
• Mis-operation of concentration calibration is automatically identified and prevented, which can avoid defects caused by human factors.
  Zero point automatic tracking, long-term use will not be affected by zero-point drift.
• Multi-level calibration of target points to ensure linearity and accuracy of measurement.
• Chinese and English interface can be selected.
• Wide working temperature: – 40 °F to 158 °F (- 40 ℃ to 70 ℃), support temperature compensation.
• Logging Record calibration log, maintenance log, troubleshooting countermeasures, reminder of the expiration of sensor life, reminder of the next concentration calibration time.
• Meet the design requirements of intrinsically safe circuit, anti-static, Anti-electromagnetic interference.
• Protection grade reaches IP66, waterproof, dust-proof, explosion-proof and shockproof.
