Oakton pH Spear, For pH Tester

The Oakton 35634-40 pH Spear is a handheld, waterproof and dustproof meter that floats, if dropped in liquid and has a replaceable, double-junction electrode for enhanced performance, with a spear tip to penetrate soft solids and semi-solids. A portable meter is commonly used to measure the pH of substance such as meats, cheeses, fruit, or wine, and is also used to test cleaning water, rinse water, and wastewater in lab, industrial, and food applications. This meter has a long, thin electrode body to use in test tubes and other narrow containers. It has three-point, push-button calibration with auto-buffer recognition of US and National Institute of Standards and Technology (NIST) standards for a wide range of results. The meter’s waterproof and dustproof housing has Ingress Protection (IP) 67-rating for protection against solid objects or liquids. It has a large, upright, four-digit LCD screen for ease of viewing. Its tactile keypad shows self-diagnostic error messages, a hold function which freezes readings for recording, error messages, a three-segment battery indicator, and an auto shut-off that turns the meter off after 8.5 minutes of nonuse.

The 35634-40 Spear-tip tester has manual temperature compensation range from 0 to 50 degrees C (32 to 122 degrees F). pH range -1.0 to 15.0, resolution 0.01, accuracy + or - 0.01, calibration up to three points US 4.01, 7.00, 10.01 or NIST 4.01, 6.86, 9.18. Its dimensions are 6.5 (h) x 1.5 (w) inches (16.8 x 3.8 cm), and it weighs 3.25 ounces. The tester works with four 1.5 V alkaline batteries (not included) for up to 500 hours of continuous use (Eveready A76 or LR44 equivalent replacements), and is used with any pH electrode with a Bayonet-Neill Concelman (BNC) connector.

pH testers measure the acidity or alkalinity of a substance. They are commonly used for water-testing, and for biological sample analysis in hydroponics, aquaculture and agriculture.
