EUTECH EcoTestr pH2 Pocket pH Tester With ATC & LCD Display
This easy to use Ecotestr pH2 by Eutech is packed with the same features as the pH1 but with the added feature of ATC and improved calibration points of 3 points.
The Ecotestr pH2 is a powerful tool without the size or cost of more advanced palm held pH meters.
The cap can be filled with buffer solution to carry out calibrations while on the move.
Large volume of polymer gel reference gives longer sensor lifespan, while single Kynar® reference junction prevents clogging.
Calibrating the Ecotestr pH2 is a doddle, just switch tester to calibration mode. Immerse sensor in pH buffer solution and leave tester to do the rest.
It will calibrate on pH 4, 7 and 10 for increased accuracy across the range.
Do I need to calibrate my tester?
Regular calibration helps to maintain tester accuracy
What is 3-point calibration?
Single-point calibration only allows calibration at one chosen point, which should be near the pH range of your application. 3-point calibration allows calibration at 3 different points (pH 4, 7 and 10) to give you ±0.1 pH accuracy across the acid and alkali ranges. If your application requires pH measurements that vary greatly, you should use this EcoTestr pH 2, which offers 3-point calibration.
Do I need Automatic Temperature Compensation (ATC)?
This depends on your accuracy requirement. Sensor sensitivity to pH changes with temperature variation. With ATC, the tester automatically detects and compensates for temperature variations.
To fulfill your order as quickly and efficiently as possible, we sometimes will split your order into a number of different packages so that we could take advantage of the items in stock at different warehouses. Items you order from Complete Safety Supplies may sometimes be sent in more than one delivery. For example, you may receive multiple deliveries if your order contains an oversized item that needs to be dispatched separately. Regardless of the number of deliveries you receive, you'll only be charged the amount that was originally quoted to you at the time you placed your order.
