How can i calculate the EC(ms/cm) from the reading in this meter? is it Hanna, Eutech or Truncheon?

FROM HM DIGITAL: The TDS-EZ uses the NaCl conversion factor, which is an average of 0.5 (from micro-Siemens). This is also (incorrectly) known as the 500 scale. Therefore, to convert from TDS in ppm to EC in mS, multiply by 0.002. For example, 1000 ppm = 2 mS.The TDS-EZ is made by HM Digital, Inc. Hanna and Eutech are other brands of instrument manufacturers and Truncheon is a particular tester made by BlueLab. Conversion factors are not company specific, but water specific. If you are looking to measure EC in mS (milli-Siemens), then we suggest you purchase an EC meter, such as HM Digital's COM-80, which can be purchased on Amazon.For more information, please visit www.tdsmeter.com and click on FAQs.

I believe you are trying to convert from the Total Dissolved Solids (TDS) concentration (units of ppm = parts per million) to the electrical conductivity of the fluid in units of millisiemens/centimeter (mS/cm). The conversion from concentration to electrical conductivity depends on the type of salt used in the solution with which the meter is calibrated. These meters measure electrical current passed between 2 electrodes and assume that the ions in the solution being tested are similar to the ions in the calibration solution when the conversion is made to ppm. According to the HM Digital meter web site, their meters are calibrated in a NaCl solution. A rough conversion is provided in the calibration instructions at URL: http://www.tdsmeter.com/TDS_Meter_Calibration_Instructions.pdf , where it is stated that "This measure of conductivity, S/cm is then converted to ppm by a factor of approximately 0.5, on a curve ranging from 0.47 to 0.55, depending on the level. The factor is related directly to the level of conductivity. This meter is built and calibrated according to an NaCl standard. Other meters may be calibrated to either a KCl standard (0.51 conversion) or the 442 standard.(0.7 conversion). " Note that this explanation refers to units of microsiemens/cm, (s/cm) instead of millisiemens/cm (ms/cm). To convert from ppm to s/cm multiply ppm by 0.5. To convert from ppm to ms/cm, multiply by 500. This appears to be close to the conversion factor used by the Hanna brand of meters.

Unable to answer this question as I have not use this feature, but would asume Temp is read in Deg's F, since other meters I have used read in Deg's F.

Don't know. I can measure Tom at office. I have 3 of them. They are great !!!

I don't know the answer, but I can recommend the Pyle CO meter I purchased at Amazon. It is excellent value and functions exactly as advertised.

Sorry Calvin, I think this a great meter, however, I only use it to check the voltage on my AA and AAA batteries and rechargeable batteries from Amazon..... Works Great ! Phil Pauls Valley, Oklahoma

I checked it with my other meter and it appears to be already calibrated. Both of my meters match.

The meter only has a guage that reads, 0 to 2000 on top and 1 to 10 on the bottom of the line...I only paid less than $4.00 for the meter including shipping from China... It has saved me from over watering. The meter seems to be working ok but I don't know how accurate it is... For a cost of less than $5.00 it can't be too percise...

I am not sure but I do not recommend this unit. The meter gauge backing came loose on mine and the laminated paper pinned against the needle, making the unit worthless.

Love this meter. Strong, accurate, capacitor reading, temperature readings, clamp on, highly suggest. Amazon has best price!

no idea how it samples all of them have to integrate over some small period to get a meaningful readingcheck the specs for A and C weighting to see if they specify the time i am sure that VU meters averaged over even longer time periods

FROM HM DIGITAL: The COM-100 is NOT a pH meter. It measures EC (electrical conductivity), TDS (total dissolved solids) and temperature. For pH, please purchase HM Digital's PH-200. For more information, please visit www.tdsmeter.com

Display usually reads 0.01-0.02 with probes in contact with each other in the 0-1K range. It is a great meter for the price.

The ones that come with the meter are .125 or 1/8 of an inch. I hope this is of help to you. Bill

I don't know. I use this for domestic applications only. I bought it because none of my old meters were Catagory 3.

Not even sure what a kind of meter that is. Sorry. I will say you will be better off buying one of the better ( Higher priced) units. You can hook the sensors right on the wires inside the circuit box in the house. This one is cheap junk with no support and are not even sold by B&D; anymore.

i am using meters fromwww.simmeters.com. they have the full set of a10c meters available on their webstore. i will be buying the wet compass from simkits.com

China. http://www.uni-trend.com/contact.html It is still very well made and the accuracy is pretty good especially at this price point. You can't go wrong with this multi-meter. I even bought a more expensive Agilent unit for $130 that didn't have miliamp readings. Sure that Agilent unit is nice, but for 2.5x the price? Not worth it. This UT61E on the other hand works awesome. Only thing I wish it had was a back light.
