Get Calibration powder 2 packages: ph4.003, ph6.864
This instrument has the following features:
First, automatic temperature compensation (ATC) (ATC means: ordinary pen need a water temperature of 25 degrees
Under state about more accurate, and ATC is not required, it will automatically measure the water temperature compensated to
The state of 25 degrees), the new document is not required to buy back the calibration,
Second, the new pen is not required to buy back the calibration.
Third, the large screen display , Measurable 2 digits behind the decimal point, both resolution
Rate: 0.01ph, note: Precision error is ± 0.1ph, we conservatively say
Accuracy is ± 0.1ph, the actual accuracy of up to ± 0.05ph
This product is our neutral packaging products
Pocket-sized digital pH meter, the introduction of advanced technology and imported components, greatly reducing the volume, reduce costs, maintain the original quality, so that the use of pH meter has been popular. High stability, high reliability, use simple, inexpensive and popular around the world, the majority of users of all ages.
Measuring range : Ph: 0.00-14.00
Accuracy: ± 0.05PH (measure 2 digits after the decimal point)
Automatic Temperature Compensation: 0 ℃ -50 ℃
Operating temperature: 0℃~ 50℃
Dimensions: 151mm × 33mm × 20mm
Weight: 60 g
The instrument has automatic temperature compensation (ATC)
Pro Tip: a glass glass electrode thinner, higher accuracy
Second, the benefits of calibration powder: Calibration powder shelf life of 5 years, and the calibration solution, if not open, only a month after the moss will, in addition to the standard requirements is the need for calibration against 250ml of distilled water (supermarkets sell) calibration can be calibrated liquid bottle only about 20ml, simply meet the requirements, but the pen when it is placed inside the calibration bottle, the bottle is too small to simply not put into, opened the calibration solution can only put 15 days on the failure, so with a good bottle of calibration solution we do not recommend using.
Note: Under normal use one year warranty, man-made damage and other costs required to repair the postage by the buyer's responsibility
PH meter glass electrode is fragile! Do not touch! Glass electrode breakage not covered under warranty!
Need instructions in English, please notify the owner, the other will be shipped only with Chinese instructions
There is no need for pH correction pen But the correction is very simple:
Note: The new pen requires no calibration, can be used directly to buy back
In the following cases, pH meter must be recalibrated:
① After calibration has been used (or place) for a long time;
② frequent use of special electrodes;
③ measurement accuracy requirements are relatively high.
④ new pen calibration is not required to buy back Oh
pH meter calibration:
1, the calibration powder with 250ml of distilled water or purified water open. The pH electrode is immersed in a mixed phosphate pH value of 6.86 standard buffer solution, and gently shake.
2, with a small screwdriver, facing pH pen behind the hole, turning left and right can be adjusted calibration potentiometer until the value of the standard buffer solution at ambient temperature, ph value of 690 matches.
3, supra electrodes inserted pH4.00 phosphorus stupid acid potassium standard buffer solution.
4, after about two minutes. PH value displayed value with the buffer solution should be in the range of allowable error compared.
Syrup Do not dirty, after calibration sealed with plastic wrap, can be reused, after calibration with pure water clean, if not frequently used, it may be 2 - calibrated once in March!
How to maintain the pH pen:
Long without words, in about half the time, the pH pen electrodes immersed in pure water, is inserted in a disposable cup can be!
1. Remove the protective cover.
2, turn the switch located on the battery compartment.
3, insert the measured liquid pH meter, until the liquid is immersed 'immersion line', conditions permitting, the solution can dipped slightly 'immersion line' position.
4, the solution was stirred gently and wait a minute or so Chung. Read the display.
5, after use. Clean the electrode. Turn off the switch. Put on protective sleeve.
