Automatic low temperature compliance meter

Overview

The low temperature compliance tester is developed for the low temperature compliance detection of waterproof coils. The instrument is made of stainless steel. The unique process ensures the temperature control accuracy is ±1 °C. The cooling speed is several times that of the ordinary freezer. The lowest temperature can reach -35 ° C. The tester is made of stainless steel. It is easy to operate and meets the national standard GB/T328.14-2007 "Testing methods for building waterproofing membranes. Part 14 · Low temperature flexibility of asphalt waterproofing membranes". This standard specifies the low temperature compliance test. The mechanical automatic test is adopted to avoid the influence of human factors. The low temperature compliance tester is a necessary equipment for detecting the quality of the product by the detection mechanism and the waterproof coil production enterprise.

Instructions

1. First place the cooling tank in the low temperature tank and add the chilled liquid "ethanol/water mixture with propylene glycol/water solution (volume ratio 1:1) below -45 °C or below -40 °C (volume ratio 2: 1) Freeze to the required temperature, then adjust the distance between the two round shafts of the compliance meter according to the test piece, ie the diameter of the bending axis + 2 m m + the thickness of the test piece, and place the test piece on the bending shaft and the bracket. It was placed in a cooled low temperature water tank, and the upper end of the test piece was 10 mm below the surface of the freezing liquid.

2. Turn on the power to the controller, turn on the power switch on the right side of the instrument, and set the temperature and time according to the standard settings. At this time, the temperature indicates the temperature in the coolant. Press the start button when the temperature reaches the set temperature. When the time starts, when the set time is reached, the bending axis starts to rise with the test piece at a speed of 360 mm/min. When the bending axis stops, the buzzer sounds, press the stop button once, the test is completed, and the test piece is checked. crack. Press the down button to bend the axis down to the starting point and press the stop button again.

Key Function

Start button: When the time temperature is set and the test conditions are ready, press the start button to test the test automatically.

Stop button: When the motor rises and falls, press the stop button to stop the motor.

Rise button: Press the up button and the bending axis will rise.

Down button: Press the down button and the bending axis drops.

Setting button: Press the setting button to set the indicator light. At this time, the left window displays the set time, and the right window displays the set temperature.

Time temperature setting

Before the test, you must set the required temperature and time according to the test requirements. The method is to press the setting button, the setting indicator lights up, the temperature window number starts to flash, input the temperature to be set, (press the up button to increase the number, press the down button The key number is reduced, press the set key, the number can be shifted), press the set key to move the number to the first digit of the temperature window to flash, up or down

The down key is -number, then press the positive number, input the time to be set, press the set key continuously to move the flashing number to the time window, press the up key to increase the number, press the down key to decrease the number, press the set key, the number After shifting, time, and temperature setting, press the stop key to save the data and the meter returns to working status. If the start button is pressed, the time is automatically cleared. When the temperature reaches the set temperature, the time starts to count. When the set time is reached, the alarm starts, and the bending axis automatically rises against the test piece. If the start button is not pressed, press the rise or Drop button for manual control

Precautions

1. When the softness meter is in operation, it is strictly forbidden to touch the instrument case directly by hand to prevent frostbite injury at low temperature.

2. When handling the test piece, put on gloves to prevent frostbite, and use the tweezers to clamp the test piece.

3. Must be grounded when using the instrument.

4. The instrument is deactivated, unplugged, and the test bucket is lifted, cleaned and stored in a ventilated and dry place.
