Thank you for purchasing the Apera Instruments PH1 Pocket pH Tester Kit. Please read this manual carefully before use in order to properly use and maintain the product. For video tutorials, please go to aperainst.de/service/support Table of Contents: 1. General Introduction .......................................................................................................................................1 2. What’s in the Kit? .........................................................................
1. General Introduction stands for stabilized reading stands for successful calibration is pH 4, is pH 7, is pH 10. Short Press (tap) 1) Power on 2) In settings, change parameter Long Press (hold for 2 seconds) 1) Power Off 2) When turned off, long press to enter settings. 3) In calibration mode, cancel calibration. 1) In calibration mode, start calibration 2) In settings, short press to confirm changes. In measurement mode, long press to enter calibration mode.
3. Preparation before Use 3.1. Prepare a cup of pure water (250-500ml) for probe rinsing. Pure water refers to tap water, RO water, distilled water, or deionized water. 3.2. Pull off the battery insulation paper; Take off the probe cap. 3.3. Perform a 2-point calibration in pH 7.00 and pH 4.00 standard buffers. Refer to Section 4 for tutorial. 4. Calibration 4.1 Short press to power on. 4.2 Rinse the probe in pure water and shake off excess water. Long press to enter calibration mode.
d) Having good-quality standard calibration buffers ready is the foundation for reliable pH measurement. The bottled buffers (50ml.) in the kit can be used for up to 10 times of calibration (make sure they are tightly closed when not in use). After that, we recommend replacing them with new ones to keep the accuracy. e) Tester will automatically recognize pH buffer solution, users can choose calibration points: 1 point, 2 points, or 3 points.
7. Technical Specifications Range 0 – 14.0 pH Resolution 0.1 pH Accuracy ±0.1 pH Calibration Points 1 – 3 points Automatic Temperature Compensation 0 – 50˚C (32 – 122˚F) Range 0 – 50˚C (32 – 122˚F) Resolution 0.1˚C /˚F Accuracy ±0.5˚C/±1˚F pH Temperature ◆ pH probes do NOT last forever. They age through normal use and will eventually fail. The average lifetime of a probe is 1-3 years depending how it is used and maintained.
Trouble Reason Pressing too soon How to fix Wait for to stay on screen before pressing .
11. Battery Replacement Please install batteries according to the following steps. *Please note the correct direction of battery installation: The Positive Side (“+”) OF EVERY SINGLE Battery MUST FACE UP. (WRONG INSTALLATION OF BATTERIES WILL CAUSE DAMAGE TO THE TESTER AND POTENTIAL HAZARDS!) 12.
