Does it have a built-in reference electrode?** A: It's a BNC type pH electrode with built-in reference. **Q: What input voltage range does this probe use?** A: They read charged hydrogen (h+) ions that get through a glass membrane. DC Milivolts **Q: How do you calibrate this device? Do you have instruction manual I can take a look at?** A: It comes with a solution that I haven't used. To calibrate, I use some Atlas Scientific pre-mixed calibrated solutions. I do a 3-point calibration using pH solutions of 4.00, 10.00, and 7.00. I swap out sensors and calibrate once a week. My software has a scale factor and an offset to use the calibration. These are great pH sensors and better than the Atlas Scientific ones I used to use. However, you will have to average over many readings to get accuracy. I take 100 readings, keep the inner 60, and then average. It takes about 7 seconds to do all that. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cheap but accurate....so far *by J***. on December 30, 2025* I used it to replace the probe on my Bluelab Guardian with no issues. Calibrated with no problem and has been working for a few months now. Quick accurate readings is all I can ask for and so far this thing is delivering at a fraction of the cost of Bluelabs probe. I'll update with any issues. ### ⭐⭐⭐⭐⭐ Works with HM products as well *by P***R on April 12, 2026* Seems to also function well with HM100 and HM200 fascist ### ⭐⭐⭐⭐⭐ So far excellent value *by R***. on December 25, 2025* Purchased as a replacement probe for my BlueLabs device. The electrode connected and calibrated perfectly and is giving consistent accurate readings. I don't know what the longevity will be, but at a fraction of the cost for a Bluelabs replacement, even if it lasts 1/2 as long it's still worth it. ## Frequently Bought Together - Long Body pH Electrode with BNC Socket Probe 300cm Cable 0-14pH for pH Meter, pH Controller pH Device Economical Sensor - Apera Instruments AI1113 pH Calibration Buffer Solution Kit (7.00, 4.00), 8 oz.
