Meet some Myron L Meters customers...

"I recommend your (Myron L) meters, both handheld and surface mount. I have used them for 20 years for TDS and conductivity / resistivity measurements. Their accuracy is dead on and requires very little maintenance aside from simple batter changes." Brian Goebel, CWS-VI - Culligan.

“I have used Myron L meters almost exclusively for my entire tenure. Very good products. I have seen continued improvements in the products as well as their life-span in a pretty grueling environment. For a water treater, I don’t believe that there are many that really even consider handhelds other than Myron L.” – Sean L. Roop, Senior Water and Process Consultant

“I have been aware of your products line for over 15 years. It seems to me that all public water treatment plants, especially membrane treatment systems should have your instruments on hand. The private sector water treatment systems all also benefit greatly from your (Myron L) instruments.” Jim Passanisi, Water Resources Consultant

The pH unit that works! July 20, 2014
Reviewer: coree coppinger from Milwaukee, WI, US
Yes this Myron L UltraPen PT2 is worth the money. The PT2 was dead on with the solution. It took a minute or two to get used to the flashing lights but then it was love at second site. A small field pH unit that was accurate and could be counted on. I relish in it's simplicity and accuracy. The bottom rubber cap has a sponge inside of it to hold the storage solution, this is smart, although the push and twist is difficult with a flexible rubber cap. This could be better designed with a hard twist cap and a O RING in the inside of the cap. I am so happy to find a unit that preforms as it is supposed to, and is dead on with the solutions. The only thing to test next is how well it preforms with time. After the ill fated experiences with the other brands being sold on the market you will find the price is much easier to swallow. It works and is accurate, that is all I ask!

Excellent Choice for Field Testers April 28, 2014
Reviewer: Aleksandar P, Water/Waste water professional from Bosnia and Herzegovina
During my work as a Field Supervisor for water plants in central Iraq region we have used Myron L's 4PII Waterproof Conductivity/TDS meters. These meters were very simple to use and easy to calibrate. They proved to be an excellent choice for our field testers. I really recommend Myron L equipment to everyone in water testing business.

Quick, Accurate Readings April 28, 2014
Reviewer: Manjit M, Project Engineer from UAE
Me & all my team uses ULTRAMETER II almost daily. It’s a great piece of equipment for Quick Accurate Readings. This handheld device is very easy to use & calibrate. Many times I use the hand held device as standard reference for my online meters, Another attractive part is the durability of the equipment - it will last for quite good period of time. Myron L products are undoubtedly reliable

A Terrific Product - Robust and Durable April 28, 2014
Reviewer: Larry L., Managing Direector from San Diego area
The Myron L Ultrameter is a terrific product - I have used them for years. The product is robust and durable.

Great Product, One of the Best! April 27, 2014
Reviewer: Env. Tech, Academic/Professional Researcher from California
I use this Hand Held many times each day. We have at least 3 on site at all times for regulatory purposes. I get accurate readings all the time in many types of water. It calibrates easier than any other handheld i have ever worked with. I keep these locked up in my office each night, because i have found over the years that leaving them in my vehicle during extremely cold conditions, or in direct sun light on hot days damages or shortens the life. I have tried several other handhelds because of a cheaper price, but none lasted more than a few months in these harsh conditions. I use these for Groundwater, Title 27 Ponds, wastewaters, fresh water, concentrated waters, and prodcut waters. I can use this one handheld for all of my monitoring.
LOVE IT! PROS: Easy Calibrations, Easy To Use, Exhibits Correct Properties, Quick Accurate Reading. CONS: NO Extreme hot cold temps
