Digitale EC, TDS en temperatuur meter tester - nieuw

Digitale EC, TDS en temperatuur meter tester.
Productbeschrijving:
3 in 1 waterkwaliteit meten pen wordt gebruikt voor het testen van het water TDS waarde, water geleidbaarheid, om te bepalen van de zuiverheid van het water.
Tegelijkertijd test zowel de temperatuur van het water en de functie van de omgevingstemperatuur.
Producten algemeen bruikbaar in water behandeling industrie, drinkwater, familie, persoonlijke home toerisme, werk op het terrein als drinkwater inspectie kwaliteitsgereedschap.
Performance indicator:
Basic functions:
- Switch / lock button (ON / OFF / HOLD) Function:
ON: In the off state, press this button to boot.
Auto-off: No operation, auto-off after 2 minutes.
Manual shutdown: press the ON/OFF button 3s to shut down.
- Press the function key to display the test water quality conductivity us / cm value, and then press once to display the Celsius temperature ℃, then press once again to display the Fahrenheit. The function selection button (MODE): the default display test water quality total solid dissolved amount ppm; Temperature ℉; then repeat the cycle to display the above.
- CLEAR key function: clear. Clear the lock read and re-test.
- Automatic test and lock reading: clear after the insertion of water can be automatically read, according to the different water quality shows the corresponding TDS value or conductivity us / cm value. And then automatically locked.
- Scale function: according to national standard scale. And with appropriate reference to international practice. Direct drinking water warning with reference to national standards using TDS = 40 for the dividing line. Less than 40 show green backlight, for qualified straight drinking water, more than 40 show red backlit, for non-direct drinking water.
- Backlight function: the use of low-power backlight, easy to night and light dark place for testing use. At the same time as a direct drinking water to determine the show.
- Large screen display: the use of high distortion STN thin liquid crystal, display 4-digit value and the corresponding physical unit.
TDS read range: 0-9999, identifier.

Grootte: 16.2 x 2.9 x 1.5 cm
Gebruiksaanwijzing:
1. take the pen and open the ON / OFF switch.
2. the pen into the solution to be measured, the solution height can not exceed 4cm (from the beginning of the pen).
3. the pen gently in the test solution to stir a few times, such as reading stability. The measured value of the TDS is greatly influenced by the temperature, so the temperature compensation is used to correct the reading. The data shows the stability of the lock automatically after the lock. To manually lock, press the HOLD key. To re-test, press CLEAR key to clear, and then re-test. Press the MODE key to achieve the test function selection, in turn select: ppm, conductivity us / cm value, Celsius temperature ℃
4. after use, with a cloth to dry the pen part of the water, the pen sets back.
5. press the ON / OFF button 3S, can be manually shut down.
