Fast, lab-accurate measurements in a handheld water quality instrument
Mar 16 2022
Ultrameter IITM instruments from Myron L®, provide a comprehensive suite of in-situ water quality analysis tools that can replace more costly and less convenient laboratory equipment.
A true, one-handed instrument, model 4P delivers Conductivity, Resistivity, TDS, and Temperature readings quickly and easily with autoranging capabilities that provide increased reading resolution across a broad range of applications. Unlike other similar meters, the 4P features the ability to select from one of three preprogrammed solution models, KCl, NaCl, or Myron L’s own 442 Natural Water™ Standard. You can also program a User solution mode based on a known solution yourself. The result is benchtop accuracy of ±1% of reading in a handheld instrument. Calibration is simple to perform using up and down arrow keys and a digital interface. And the 4P is IP67 dust-tight and waterproof, NEMA 6 submersible, and buoyant.
Model 6PFCE includes all features of the 4P but adds the ability to measure pH, ORP, and Free Chlorine Equivalent (FCE™). pH readings are temperature compensated, and you can choose to perform a 1-, 2-, or 3-point calibration depending on the range of samples measured to achieve ±.01 pH accuracy. The pH sensor is of a proprietary construction and includes a large potassium chloride solution reservoir for long life. Myron L pH sensors are also user replaceable. ORP measurements utilize a 99.9% pure platinum electrode and a reference junction that is shared with the pH sensor. ORP accuracy achieved is ±1 millivolt. In addition, the 6PFCE features a groundbreaking new way to determine Free Available Chlorine. Get empirical measurements of the chemical activity of a solution without the hassle and subjectivity of colorimetric and test-strip methods. The FCE measurement is the fast accurate way to determine the killing power of free chlorine species in water. It employs a proprietary predictive ORP algorithm to determine free available chlorine levels at the actual pH of water, so you know your chlorine treatment is effective.
