The large surface area of the HI11312's spherical pH glass tip makes it perfect for general use in aqueous applications.
Buy NowA spherical glass sensing bulb housed in a durable, plastic PEI body allows the HI12302 to be ideal for taking laboratory accuracy on the go.
Buy NowThe HI12922's triple ceramic junction paired with a conical, low temperature glass tip ensures fast stabilization of readings without compromising accuracy.
Buy NowA refillable glass body and spherical general purpose glass sensing bulb make the HI11102 perfect for measuring pH across the breadth of the pH range in water samples.
Buy NowTest pH and temperature throughout your beer making process without fear of clogging your electrode. The FC2142 sports a strong titanium body with a flat sensing tip and renewable junction bringing an ease to testing at any beer stage.
Buy NowThe HI10482 utilizes the Clogging Prevention System (CPS) technology™ with the PTFE sleeve junction making wine pH testing fast, easy, and clog-free.
Buy NowDesigned with to test pH levels of food, the FC2022 has an open junction to resists clogging, an easy to clean body, and conical tip for easy insertion into food.
Buy NowThe conical glass tip on the HI10532 lends itself to easy, direct pH measurement in semi-solid foodstuffs.
Buy NowTesting on flat surfaces has never been easier than with the HI14142. An open junction with a flat tip gives the electrode speedy response times and accurate results.
Buy NowThe tapered body and small spherical glass bulb gives you excellent accuracy when testing in vials, test tubes, and other small vessels.
Buy NowOur microbulb tip on the HI10832 is the epitome of small at only 3 mm; it is optimal for use in 96 well plates, microcentrifuge tubes, and more.
Buy NowSince 2014, Halo provides small business owners and hobbyists a simple tool for high quality pH monitoring in the home or at work.
Easy and convenient to use. Calibration, reading, and maintenance are unbelievably simple. Record keeping is done automatically for you.
The HALO is perfect. If you are a hobbyist or a small commercial cheese maker this is the most cost effective tool and if you are a pro it is still perfect......very cool!
The marriage of Bluetooth® HALO pH meter with connected electronics really changes the face of what the future of handheld environmental monitoring will look like.
Depending on the nature of your samples, your pH electrode can become dirty or clogged resulting in slow and faulty readings. Regular cleaning will prolong the life of your electrode.
Shop NowTo ensure your pH measurements are accurate, be sure to calibrate after extended storage, cleaning, and before use. Use fresh buffers that bracket your expected value.
Shop NowA dry electrode results in slow, incorrect measurements. Always use the proper storage solution and be sure to fully cover the junction.
Shop NowAn essential step in achieving accurate pH readings is proper calibration. A clean, calibrated, and conditioned pH electrode will provide accurate and repeatable results. When calibrating a pH electrode it is important to choose buffers that “bracket” (are above and below) the expected reading.
For example, if the expected reading is pH 5.4 then it would be best to calibrate to pH 4.01 and pH 7.01.
We manufacture a wide range of buffer solutions for a variety of uses. Visit our blog to find out What Type of pH Calibration Solution Should You Use?
