CDI309Ex Intrinsic Safety Infrared Thermometer
1. Product Overview
The CDI309Ex intrinsically safe infrared thermometer is a high-precision, durable and easy-to-operate non-contact thermometer. It can quickly and accurately determine the surface temperature of the target by measuring the infrared energy emitted by the target surface. It is also waterproof, dustproof, explosion-proof and shock-proof. It is widely used in industries such as petroleum, chemical engineering, environmental protection, smelting, gas transportation, and biotechnology.
2. Product Features
(1) Sturdy and Durable: Passed the 3-meter drop test.
(2) Dustproof and Waterproof: Achieved an IP65 rating for dust and water resistance.
(3) Ergonomic Design: Comfortable and natural to hold, with simple and quick operation.
(4) MAX/AVG/DIF/MIN: Quickly displays maximum, minimum, and average values, as well as the difference between the maximum and minimum values during measurement.
(5) Large Backlit Display: A wide screen with large digits and uniform white backlight ensures clear and bright visibility.
(6) Alarm Function: High and low-temperature limit alarms are indicated by LED and character flashing, allowing quick identification of out-of-range measurements.
(7) Dual-Wavelength Rotatable Laser Indicator: Equipped with a dual-wavelength rotatable laser to help accurately and quickly identify the measurement area.
(8) Data Storage Function: Can store up to 99 sets of measurement data, facilitating analysis of results.
(9) Scheduled Measurement Function: Set a specific time for the device to automatically power on and measure once daily.
(10) Monitoring Measurement Function: Set a time interval for the device to automatically power on and measure at regular intervals, saving labor.
