Thermometer UNI-T UT309A PRO Line

Product detailed description

The UT309A professional non-contact infrared thermometer can quickly and accurately determine surface temperatures between -35°C and +450°C by measuring the infrared energy emitted from the target surface. The UT309A is a very durable instrument suitable for everyday use. It is drop resistant from 3m and the excellent IP65 rating ensures good water and dust resistance. The UT309A has a fixed emissivity of 0.95 and a single aiming laser to indicate the correct aim of the thermometer. The distance to diameter ratio of the surface to be measured is 10 :1 for this instrument. Indication of preset functions and measured temperature values is provided by a high-contrast LCD black and white display, and exceeding the temperature limits is indicated by LEDs ( exceeding the upper limit red and lower limit blue ). It is possible to set up continuous measurement, where after 2 minutes the display backlight is switched off, after the measurement is finished by pressing the trigger again the temperature value remains on the display. The temperature measurement time is in 95% of cases within 250msec. Indication of minimum, maximum and average temperatures and the difference between the highest and lowest measured temperature ( MIN, MAX, AVG, DIF ) is possible. The thermometer switches off automatically, to reduce power consumption, if it is unused for 8 s. This switching off can be disabled. - Drop resistance from 3m - Degree of protection: dust and water resistance IP65 - Large LCD display with backlight - MAX/MIN/AVG/DIF modes - High/Low temperature alarm with LED indication - Continuous measurement - Data hold - Thread for tripod connection TECHNICAL SPECIFICATIONS: - Temperature range: -35°C to +450°C (-31°F to 842°F) - Temperature measurement accuracy greater than or equal to 0°C: ±1.8°C or ±1.8% of measurement, whichever is greater - Temperature measurement accuracy <0°C: ± (1.8°C + 0.1°C /°C measurement, whichever is greater) - Temperature measurement accuracy greater than or equal to 32°F: ±3.6°F or ±1.8% of measurement, whichever is greater - Temperature measurement accuracy <32°F: ± (3.6°F + 0.1°F /°F measurement, whichever is greater) - Temperature measurement resolution: 0.1°C - Measurement Repeatability: ±1.0°C (1.8°F) or 0.8% reading, whichever is greater - Spectral response: 8µm to 14µm - Response time 95% of the time: 250 ms - The distance to diameter ratio of the surface to be measured for this instrument is 10 :1 - Laser delineation of the measurement area: yes - Class 2 laser: wavelength 630nm to 670nm, output power ?1mW - Display: 32 x 29 mm contrast black and white LCD display - Temperature limit indication by LED (red, blue) - Fixed emissivity of measured surface set to 0.95 - Automatic shutdown in case of inactivity - Power supply: 9V battery (6F22) - Battery life: continuous temperature measurement with backlight on ?12 hours - Low battery indication: yes - Drop test from height: 3 m - HI/LO temperature alarm mode (High/Low alarm with LED indication) - MAX / MIN / AVG / DIF value suspension - Operating temperature: 0°C to 50°C (32°F to 122°F) - Operating Humidity: <90% RH (non-condensing) - Operating altitude: max.12000m - Storage Temperature: -20°C to 60°C (-4°F to 140°F) - Product Color: Red and Gray - Net product weight: 292 g - Product dimensions (l x w x h): 189 x 118 x 55 mm FUNCTIONS: - °C/ °F selection - Laser shutdown - Display hold: 8s - Automatic shutdown - Low battery indication - Continuous measurement - MIN,MAX - Difference - Average - High temperature alarm (red LED) - Low temperature alarm (blue LED) - Power-off memory PACKAGE CONTENTS: - Thermometer - 9V battery (6F22) - Instructions for use
