Meters.... PH,TDS,PPM.......ECT.

[keithrs]

I was wondering what meters you guys use for PH,TDS,PPM,EC, and temp.

For TDS/EC I use a Hanna TDS probe:

It measures EC but reports it as TDS.

For temperature and humidity I use Extech meters:
Extech Instruments - Humidity Meters - Humidity Indicators

For pH I use ColorpHast brand pH indicating strips:
pH Test Strips

Thanks for responding.... I'm going to start using EC to check my fertilizer.

Do you have any experience with Hanna Instruments Hi 98129 Combo Ph /Ec/Tds/?C Tester. I was reading a article writen by David Mellard and this was one he recommended.

[DavidCampen]

I don't have any experience with the combination meters.

pH meters require more care than EC/TDS meters and I use the TDS meter much more often so if I were to decide that I wanted a pH meter instead of pH test strips I think I would want a separate pH meter.

I am happy with this meter:
Amazon.com: Mastech Digital Illuminance/Light Meter LX1330B , 0 - 200,000 Lux Luxmeter: Home Improvement

Previously, I bought this meter but thought it was junk:
Light Intensity Meter - TekSupply
