Selected User Reviews For Windshield Washer Hydrometer
a solution of water Readings can be repeated if proper precautions are taken to avoid the formation of air bubbles on the swing arm. The temperature compensation seems to be excellent. The main flaw is that the calibration isn't quite right. I'm wondering if the 0°F mark was calibrated with bubbles on the swing arm, given that it's off by 23 rotational degrees. A 5-star rating would be given to this hydrometer. If the calibration was better, I would give it a five-star rating. Even after adding my own calibration marks, I still find it useful as is. br>It's difficult to read the official instructions embossed on the tester. They are displayed as follows:
E- Instructions for using Z REDbr>1. 2. Fill the Tester all the way to the line. br> To dislodge bubbles from the float, firmly tap the case.
3. Hold the tester vertically, with the liquid level parallel to the line that runs across the top of your face.
4. Number is read from the float's index line. br>To clean, run a detergent solution through it. br>br>My preferred instructions are as follows:
1. Squeeze the bulb completely closed while the suction tube is out of the fluid.
2. Place the suction tube in the fluid (it's best to keep it submerged throughout the measurement to avoid bubbles).
3. Allow the bulb to fully expand before slowly releasing pressure. As the fluid enters the tester, keep an eye out for bubbles. If a bubble forms, squeeze the bulb slowly to lower the fluid level until the bubble is exposed to air, then slowly let the bulb expand.
4. To make sure the swing arm is free, wiggle or tap the tester. It should wobble slightly above and below the reading.
5. Hold the tester vertically and parallel to the fluid surface with the line at the top of the face. If the fluid level is too high, gently squeeze the bulb until the fluid surface is visible, then level the tester.
6. Read the number that corresponds to the swing arm's index line (or interpolate between adjacent numbers). br>br>Erratic Readings &amp br>To avoid erratic readings, fill the tester slowly and carefully, keeping an eye out for air bubbles. As fluid rises past the swing arm's hole, keep a close eye on it. A bubble can become trapped in the hole if fluid rises quickly past it. Keep an eye on the right-hand side of the screen. The hand edge of the swing arm is where bubbles are most likely to form. One almost imperceptible bubble clinging to the swing arm adds enough buoyancy to sway the reading significantly. The best way to avoid attached bubbles is to take the first measurement very carefully – as instructed in my preferred method. When bubbles form, they almost always form right next to the pivot, resulting in high freeze temperatures. br>br>Calibration & br>The true 32°F mark is 5 degrees clockwise from the mark. The true zero degree of Fahrenheit is 23 angular degrees clockwise from the mark. The - The 21°F point is 12 degrees clockwise from the 0°F point.

1. The following marks are on the scale: Scale: °C/°F: 0/32, - 11/12, - 17/0, - 31/- 25, - 51/- 60
2. Temperature compensation: The scale divisions range from 12 to 35 Fahrenheit degrees. br>br> At 4°F and 68°F sample temperatures, a fluid sample with a 0°F freeze point measured the same. At least for this sample, the compensation is excellent over this range! Tips: br>br>
1. Above-mentioned fluid has been labeled for optimal performance. The methanol concentration of 30% to 35% of C2?F is usually between 30% and 35% of 30% of 35% of 30% of 35% of 30% The weight of volatile organic compounds in windshield washer solutions is 35% by weight in federal regulation. According to a Methanol Institute chart, the corresponding freeze points are - Temperatures range from 15°F to -15°F. 25°F. You can expect a new fluid labeled for use at - to arrive soon. The freezing point of water at 20°F and above is -. Temperatures range from 20°F to -20°F. Because your new fluid has a temperature of 25°F, you can use it as a rough calibration point.
2. It's possible that the suction tube won't be able to reach the reservoir's liquid level. Lifting the rear wiper and placing a sample bottle under the nozzle while an assistant runs the washer is one method of sampling the fluid.
3. Fluid from the rear window nozzle may have a higher freeze point than fluid in the reservoir at first (I've seen a difference of up to 18°F). If the first fluid you draw has a high freeze point, either discard it or return it to the reservoir and draw more. It appears that the methanol escapes from the reservoir to the rear window nozzle over time via the long rubber tube.
It really works. I used it to see if the fluid in my tractor tires had a freeze point. If you have windshield washer fluid in your tractor tires, this is a good thing to have on hand.
Commercial images were included. tap water, 5% MeOH from yellow HEET, 10% MeOH 1tsp 20/10 brand conc T880, and 5X of 20/10 brand conc T880 for calibration (with bubbles and after 5 min.
In line with expectations.
WORK WELL.
THIS THING WORKS LIKE A CHARM!.
I work as a Parts Manager for a busy quick lube dealership. We always top off the washer fluid as part of our routine fluid checks. This can be a significant cost for the shop supply budget, so we're always looking for ways to cut costs. One option is to buy washer concentrate in bulk, but the only issue is regulating the mixture. This item has helped us keep the mixture consistent and at a low enough freezing point that we don't have to worry about customer issues. Overall, this item has exceeded my expectations.
Methanol percentages are not read correctly by this product. It's difficult to read the meter because it jumps up and down. Because our field workers were complaining so much, we decided to test it in our lab. We eventually came to the conclusion that they should be returned.
