NEW! FCE FAC Function
The Myron L Company FCE function reports FAC quickly and accurately by measuring ORP, the chemical characteristic of chlorine that directly reflects its effectivity, cross referenced with pH. Both DPD kits and colorimeters may tell the user the FAC value of the sample in the test tube, but since the chemistry of that sample is quite different from the source water being analyzed, the results are imprecisely related to actual disinfection power. The Myron L Company FCE function measures the real, unaltered chemistry of source water, including moment-to-moment changes in that chemistry.
One-touch measurements for conductivity, resistivity, TDS, ORP, free chlorine, pH and temperature
User-intuitive prompts step you through alkalinity, hardness and LSI titrations
LSI Calculator accepts both grains and ppm hardness units
4-electrode conductivity cell eliminates polarization, increasing accuracy with minimal maintenance
Microprocessor-based surface mount circuitry
pH/ORP glass sensor is user-replaceable
Various solution modes provide accuracy in diverse water quality applications
Auto-off that minimizes power consumption (one 9 V battery lasts up to 100 hours/5000 tests)
Proprietary temperature compensation and TDS conversion algorithms
Non-volatile microprocessor provides data back-up, even when the battery is changed; this assures all calibrations and memory data are retained
ORP / Free Chlorine
Langelier Saturation Index with Calculator
Since 1957, the Myron L Company has designed and manufactured highly reliable analytical instruments for a wide variety of demanding applications. Thousands of professionals around the world rely on the performance of our instruments every day. Uses range from boiler water testing to ultrapure water control to medical instruments for artificial kidney machines. We are proud of the trust our handheld instruments and monitor/controllers have earned. Some of our instruments have been in continuous use for over 40 years. Our latest digital handheld, the Ultrameter III 9P, is based on the tried and tested design of the Ultrameter II. The 9P adds the ability to perform in-cell alkalinity and hardness titrations either as stand-alone measurements or as part of an LSI calculation. Alkalinity, hardness, pH and temperature values can be manipulated in the LSI calculator to predict the effect of changes on water balance. Measurements are extremely accurate. And the 9P is simple to operate and maintain.
Accuracy You Can Trust
The Ultrameter III delivers exceptional accuracy of ±1% of reading (±.1% at calibration point). This high level of accuracy is achieved through advanced four-electrode conductivity cell technology, a powerful microprocessor, proprietary circuit design and conversion algorithms for three of the most common solution types, as well as a unique pH/ORP sensor. With displayed values of up to 9999, the full four-digit LCD ensures resolution levels never before possible in such affordable instruments. For accuracy in diverse applications, Ultrameter III allows you to select from 3 solution modes that model the behavior of the most common solution types: KCl, NaCl and 442 Natural Water. Additionally, the Ultrameter III features a user adjustable conductivity/TDS conversion ratio for greater accuracy when measuring solutions not contained in the microprocessor. Factory calibrated with NIST traceable solutions, each Ultrameter III may be supplied with both certification of traceability and NIST traceable solutions for definitive calibration.
Free Chlorine Readings
The Ultrameter III features the ability to convert Oxidation Reduction Potential measurements from mV to parts per million (ppm) free chlorine. The mV to ppm free chlorine conversion algorithm is based on a published conversion curve and bench testing performed at the Myron L Company. The accuracy of low-range ppm free chlorine readings has been increased by extrapolating from the published data. With this new feature Myron L instruments can measure a dynamic range of sanitizer concentrations that is wider than the range of a colorimetric test kit.
The Ultrameter III is a prime example of how high-tech engineering can greatly simplify and streamline a task. Whether in the lab, industrial plant, or in a remote field location, electrometric measurements are accomplished in 3 easy steps:
1. Fill the cell cup
2. Push a parameter key
3. Take the reading
Temperature compensation and range selection are both rapid and automatic. User adjustable temperature compensation (up to 9.99%/'C) which can also be disabled for applications requiring non-compensated readings. Digital results display instantly. Measurement is continuous, displaying real-time readings rather than a static snapshot of the solution.
Easy to Calibrate
All calibrations are quickly accomplished by pressing the UP or DOWN arrow keys to agree with our NIST traceable Standard Solution. When calibration is necessary, display prompts simplify pH calibration and make sure the correct buffer is being used. Plus, all parameters (excluding factory set temperature) have an internal electronic setting that can be used for field calibration and as a check on pH/ORP sensor life.
In-Cell Titration Functions
The Ultrameter III adds the ability to perform in-cell conductometric titrations that provides a convenient way to determine alkalinity, hardness and LSI in the field. This eliminates the need to collect and transport samples to another location for analysis. User intuitive display prompts guide you through titration procedures from start to finish. All required reagents and equipment are included in the 9P titration kit.
Water Balance Analysis
The Ultrameter III features both an LSI Calculator and an LSI Titration measurement mode. The Calculator allows you to perform what-if scenarios to predict how changes in solution parameters would affect the water balance of a system. The titration measurement function allows you to accurately calculate a saturation index value of a specific solution to determine whether the solution is balanced, scaling or corrosive. Hardness Unit Conversion The Hardness titration, LSI Titration and LSI Calculator functions allow you to set the hardness unit preference to either grains of hardness or ppm CaCO3.
