The Hydrion Insta-Chek pH Pencil is used to measure the pH of any surface or solid. It measures from pH 0-13 in full pH unit increments. No technical training is necessary. To measure the surface pH just wet the surface with distilled water. Stroke the surface with the pencil. Wait approximately 30 seconds and compare the resulting color change with the color chart. The pH Pencil is used to detect acid or alkali residues and may be used to measure the pH of any of the following: Paper, Lumber, Concrete, Cement, Plasterboard, Pre-painted surfaces, Painted Surfaces, Textiles, Skins or Ceramics.

QUANTOFIX test strips are semi-quantitative in nature. They meet all requirements for a modern rapid test. Most of the QUANTOFIX test strips can be carried out in 10-120 seconds. That makes the application very quick for the end user. All QUANTOFIX tests are ready to use kits. They are precalibrated and contain all necessary equipment and reagents. As "labs in a pocket" they are very handy for the end user. The color charts are adjusted and checked using certified standard solutions that are directly traceable to primary NIST standards. The user can be sure to receive accurate readings whenever he tests. Make sure to store the packs in a dry, cool place at 39-86 °F (4-30 °C). Some tests are separately marked to require cool storage at 39-46 °F (4-8 °C). To ensure the longevity of the test strips, please close the tube immediately after removing a strip. The desiccant in the stopper effectively protects the strips against moisture. The strips can safely be used up to the date printed on the pack. The initial shelf life of the QUANTOFIX products is 2.5 years after production.

Comes with a complete kit of premixed calibration solution (pH 7.00), AAA batteries in a portable carrying case. Auto power-off in 10 min if no operation, low-battery alarm. IP57 waterproof and dustproof, floating on water so you don’t have to worry if it falls into water by accident. 1000 hours' continuous operation (without backlit) powered by AAA batteries. The meter is CE certified and comes with a 2-YEAR Warranty (6 months for the probe). The company designs and manufactures scientific analytical instruments like meters and sensors for pH, conductivity, turbidity, and dissolved oxygen for over 25 years, and meets ISO 9001:2008 Standards. NOTES: The instrument will NOT give accurate or stable readings for distilled or deionized water's pH testing. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. To measure distilled or deionized water’s pH, users need to use a specialized pH electrode. Do NOT store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for cleaning the pH probe.
