Review on 📊 Milwaukee MW102 PH Temperature Meter: Reliable Accuracy for Precise pH and Temperature Measurements by Julian Davidson

I use a PH meter for hydroponics. In the last 2.5 years I have tried several PH meters from different manufacturers. I had an HM PH200 digital pen and had to constantly replace the probe, some cheap yellow Milwaukee pens that just died and a few more $50 meters. Needless to say I was very disappointed. Due to faulty sensors and devices that cannot be calibrated, I will never be able to achieve accuracy. I finally had enough and after a bit of research I decided on this one based on the price and the reviews. So far I am very satisfied with this device. I have more confidence in the calibration and readings of this device. During calibration you need to calibrate this gauge to 7.01 and then calibrate the slope to 4.01. I haven't seen this with other gauges, but once calibrated the instrument is very accurate and calibrates with no issues. It might sound complicated, but calibration is pretty easy. I usually do a recalibration after about a week, but when I decide to recalibrate, I find that it doesn't differ by more than 0.02, which is within acceptable limits. However, I will recalibrate it anyway as I still have the solution. I also like that this meter uses temperature to adjust PH accordingly, which improves accuracy. Not all gauges, especially the cheaper ones, give correct readings based on temperature. My last pen had a small sponge in the cap that dried out pretty quickly, so even when storing it I had to check it often and reapply the storage solution to keep it from drying out. However, this meter has a small bottle that fits over the probe and contains a large volume of solution that can be stored when the meter is not in use. I feel like I can store this device much longer with the solution bottle on the sensor without checking it and letting the sensor dry. I love that it has a little hourglass display that tells you when you're done reading. Reading sometimes takes time, especially with moving liquids. However, in a stagnant liquid with no movement, you will get a reading fairly quickly. I leave the sensors in the sample I'm testing for a while (5-10 minutes) and then take a reading. I have found that I get more consistent and accurate readings when I do this. The cables on the sensors are long, which is good, but the device is a bit large and holding the device together with two sensors to take measurements is a little more awkward than with affordable pen meters. Because the cables are a decent length, you can stand the device and just hold the probes, making it easier to use. some electrical tape where the wire meets the connector to reduce stress on the cable. But even if they fail over time due to continuous use, replacement sensors are quite cheap compared to some flow meters. I'm only interested in accurate measurements as PH is very important in hydroponics. While this gauge isn't the most user-friendly, I have more confidence in the readings I get using this gauge and its accuracy shows in my garden. I highly recommend this device.
