  • How often do you calibrate your (Hanna) Ph meter? | Reef2Reef
    My PH has always read between 8 and 8 5 more or less I tested today with my "cheap" meter and Hanna meter at the same time Cheap meter read 8 3 Hanna read 8 6 Calibrated the Hanna and it read 8 0 I figured either way it will work it will just be consitantly off? Or at least I'd hope
  • Which PH meter should I buy? | Reef2Reef
    Next, I calibrated the YINMIK pH meter and now it agrees with the "inaccurate" one A cheap API test kit has my entire family agreeing that none of the colors really match up correctly At this point I'm a bit spun around and I don't know what to think A little research says some of these tools claim to be accurate by + - 4 What?!?!
  • Kactoily 7-in-1 Monitor | Reef2Reef
    2 pH: Very consistent when tested against Salifert's pH test kit (ie, within a tenth of a decimal point every time) I tested 5 times during the 4 week test period 3 Specific Gravity: Lower when checked against my refractometer and Hanna checker--both of which I calibrated against reference solution once a week for confirmation purposes
  • pH Measurement - Hanna vs Apex | Page 2 | Reef2Reef
    So trying to maintain ph range so bought Hanna tester just to see what the values would be versus my calibrated ph probes (7 and 10 stds) I calibrated the pH probes twice with 7 10 standards after allowing them to get to tank temperature How accurate is the Hanna meter? Instructions mention accuracy + - 0 2 pH
  • How Often Do You Calibrate Your Ph Probe s? | Reef2Reef
    A ph probe is an invaluable tool that can give us a snapshot of tank health However, it is only useful if the data we get from it is accurate On many occasions, I’ve seen a number I like and assumed it was correct Then I do my routine calibration and get the real number, sometimes finding out
  • best Digital PH meter? | Reef2Reef
    Milwaukee pH Meters - Official US Site Test the acidity or alkalinity of sushi rice, soil, hydroponics systems, aquariums, beer, wine, cheese, and more with a Milwaukee pH meter Our pH meter range includes everything from affordable pH pens and advanced pH testers to lab grade pH meters, monitors and controllers
  • How often to recalibrate pH probes? | Reef2Reef
    How often do you guys calibrate pH probes? My Alkatronic suggests every 8 months, but the Hydros controller suggested every 3 It's been 90 days since I setup my hydros, so I calibrated both probes today and was surprised at how far the readings had drifted both were off by about 0 2-0 3
  • PH gt; 8. 6, should I avoid it? | Reef2Reef
    A higher ph can cause the chemical equation to move the opposite direction and negatively impact coral calcification This isn’t entirely supported I run my tank sps frag tank 8 4-8 8 The probe is calibrated quarterly In general it is a good guideline to follow, but it doesn’t cause “the chemical equation to move the opposite direction”
  • how often do you recalibrate your hanna checkers?? | Reef2Reef
    They are calibrating their response to the color of the water in the first vial, perhaps zeroing or taring out the meter before the test reagent is applied In contrast, pH meters may have an adjustment that can be made by comparing the pH meter reading against known standards and dialing in the reads to “calibrate” the probe and meter
  • DIY Boron Test | Reef2Reef
    Plus, you will already have the necessary calibrated pH meter, and you will already be familiar with ordering standardized reagents, such as the 0 1N standard acid used
