The 2 required voltages of popping one's head in are 12V.
Utilize electronics double glazing dew point testing instrument of the present utility model to test below:
1, test principle:
Cool off the glass surface part after placing dew point hygrometer, and after reaching uniform temperature, internal steam is in a cooling point position dewfall, and this temperature is dew point.
2, test procedure:
The first step: at first will be to water filling in the water tank (it is empty that the equipment water tank is initially), concrete grammar: locate to insert a flexible pipe at " water return outlet ", the tap water place has been received in the flexible pipe other end, toward the water tank water filling, if there is not tap water, can utilize the siphon method to add pure Shui, have Shui to flow out until spout hole, cut off the water supply rapidly, water filling finishes, pull out water pipe (by the quoit of rapid-acting coupling, extract water pipe then inwards, can't pull out firmly).In this process, switch is necessary for closed condition on the panel.
Second step: two aviation plug two ends are inserted electric appliance control box and probe respectively, electric appliance control box " water return outlet " is connected (arbitrarily insert) with flexible pipe with last two interfaces of probe with " water delivering orifice ", plug at last.
The 3rd step: open the switch that is denoted as feedwater and switch on (if finish under first and second situations about going on foot under summer or the environment temperature condition with higher, can open the refrigeration switch in advance, preset 30 ~ 60 minutes, open again and be denoted as to taps energising) observe white water pipe and there are flowing out and flow into, open the switch of refrigeration switch then, open gauge tap again, start probe, after can treating in advance that the instrument displays temperature reaches setting value and approaching stablizing, to be pressed on the sample on the probe, this moment, probe temperature can rise, keep a period of time etc. stable back, retention time is pressed the regulation of table 1, if temperature exceeds-40 degrees centigrade, will make it reach standard-required by adjusting setting value.
Table one: the thickness of test Central Plains sheet glass and tabulation duration of contact
| Former sheet glass thickness mm | Duration of contact/min |
| ≤4 | 3 |
| 5 | 4 |
| 6 | 5 |
| 8 | 7 |
| ≥10 | 10 |
Reach the stipulated time, remove dew point hygrometer probe, have or not dewfall or frosting on the inside surface of sight glass sample at once, if 20 blocks of sample dew points all≤4 degrees centigrade, then be qualified.
The 4th step: off-test, by from left to right closing one by one in proper order, pull up aviation plug (the electric appliance control box place can not pull out) and water pipe, probe is put back to original position.
Technical parameter comprises: technical parameter: temperature range :-40 ℃, measuring accuracy: ± 0.5 ℃, principle of work: adopt mode, control mode with combined electronic refrigeration+refrigeration unit refrigeration: intelligent temperature instrument control Automatic Control, and simple to operate.Stability: can stablize control-40 ℃ temperature, be beneficial to the result and judge.Version: box.Application scenario: laboratory+scene.
