Hanna Instruments HI HI9813-5N Waterproof pH/EC and TDS Meter Review

Hanna Instruments HI HI9813-5N Waterproof pH/EC and TDS Meter Feature

• Portable and water-resistant pH meter designed for agricultural applications
• Cal-Check feature to check calibration status
• Automatic Temperature Compensation (ATC) to eliminate need for extra calculations
• Battery Error Protection System (BEPS) to alert user of low battery and potential error
• On-screen user and calibration guides for ease of use

The HI 9813-5N Waterproof pH/EC/TDS Meter is a multi-parameter pH meter designed for agricultural applications such as hydroponics, greenhouses, farming, and nurseries.

Featuring a large, easy-to-read LCD screen, the tester provides fast and accurate pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature readings in a single, portable waterproof device. Calibration is simplified with calibration dials and instructions located on the front of the device. Hanna’s exclusive Cal-Check feature allows users to simply press a button to check the calibration status at any time. If the meter is calibrated, a message will indicate “Probe is OK”, but if the meter needs cleaning the device will direct the user to “Clean Probe and Calibrate”.

The HI 9813-5N tester functions in temperatures of 0.0 to 60.0 degrees C, and has a range of pH 0.0 to 14.0 (+ or - 0.1pH) with a resolution of 0.1 pH. For EC, the device has a range of 0.00 to 4.00 mS/cm (+ or - 2% F.S. mS/cm) and a resolution of 0.01 mS/cm. For TDS (total dissolved solids), the device has a range of 0 to 1999 ppm (mg/L) (+ or - 2% F.S. ppm) and a resolution of 1 ppm (mg/L). The attached HI 1285-5 polyprolylene probe features a fiber junction and gel electrolyte to prolong the life of the device.

pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.

Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries located in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including the world’s first pH electrode with a built-in temperature sensor, electronic pocket-sized pH tester, and replaceable electrode pH pocket tester. To ensure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying viewing abilities. A trinocular eyepiece is used to output digital images to an internal or external device such as a camera or monitor. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also use LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.

Aven manufactures optical inspection tools, precision tools, and bench accessories for industrial, scientific, and research applications. The company was founded in 1983 and is headquartered in Ann Arbor, MI.
