UNI-T UT121B | Smart Digital MultimeterThe UNI T UT121B Smart Digital Multimeter is an ultra thin True RMS meter for electrical maintenance, electronics service, home users, and technicians who prefer smart automatic measurement. It provides AC voltage up to 750V, DC voltage up to 1000V, resistance up to 60M, capacitance up to 60mF, frequency, temperature, NCV, LIVE detection, dual display, flashlight, and auto range operation. Pro Tip Use smart identification for quick checks, but

" and the meter handles the entire chemical titration to perfection

Utilizing the Zinc Reduction Method

The pH meter is used during sample preparation and to determine the titration endpoint

serving as an indispensable QA tool for monitoring the nitrogen cycle in commercial marine hatcheries and high-end reef tanks

Unlike the HI38000 low-range sulfate kit

lightweight design makes it ideal for overhead work or tight spaces where heavier 18V tools would be cumbersome

Dynamic Dosing Algorithm: Automatically slows down the titrant dispensing speed as it approaches the endpoint

making it the ultimate tool for commercial car wash stations

The digital pH electrode (such as the HI11310) is purchased separately

no batteries or charger included)

RO pretreatment checks

Use the guide assembly for long straight edges
