The 4HA73127 spare pH sensor makes electrode replacement quick and easy. The spare pH sensor is designed as an easy-fit cartridge that locks into place, featuring two o-rings to maintain a watertight seal. With no pins to line up or that can break, this sensor is ideal for quick replacements.

The 4HA1271 is the Spare pH Electrode for 4HA98100 / 4HA98103 Checker^® pH meters. Replacing the pH electrode is both quick and easy. Simply unscrew the old probe to be replaced and screw on the new one. The 4HA1271 is a single junction pH electrode that has a slim 8 mm polypropylene body that easily fits into test tube and other small sized vessels.

The General Calibration Bundle is great for customers who value field calibration and more importantly, fresh buffers. This bundle has the added value of being able to ensure fresh buffer every time you calibrate for accurate results and expires after 5 years from manufacturing. Includes 4.01 & 7.01 pH Buffer Sachets (25 pieces each); Electrode Storage Solution (500 mL); General purpose Cleaning Solution Sachet (25 x 25 mL).

The General Calibration Bundle (4HA547-11PB) is great for those who frequently calibrate in a lab or other controlled space. The two calibration points at pH 4.01 and pH 7.01 set it apart for users who only want to calibrate two points and save on solutions they would not use. Includes 4.01 & 7.01 pH Buffer (500 mL/each), Electrode Storage Solution (500 mL), General Purpose Cleaning Solution (500 mL).

4.01 / 7.01 / 10.01 pH Value @25°C (500mL Bottle). Air-tight bottle with a tamper-proof seal of freshness to ensure quality. Opaque bottle reduces light exposure that could alter the buffer value.
pH 4.01 buffer value is widely used in water purification plants, in the food industry, and wherever the pH is expected to be slightly acidic.

pH 7.01 is the most widely used among all buffer solutions. For this reason we have prepared it in a wider variety of sizes to meet your application needs.

pH 10.01 buffer solution is commonly used to calibrate equipment used for analyzing basic samples.

4.01 / 7.01 / 10.01 pH Value @25°C, (25 pieces X 20 mL Sachets). Each sealed sachet holds just the right amount of solution making every sachet as fresh as the day it was packaged! Perfect for use with testers and portable meters!
