Description
T500-4 lithium battery is a rechargeable lithium battery (3,7 V) intended for the turbidity meters TN500 and TN420. Simple to install, it serves as a direct replacement power source that restores instrument readiness for turbidity measurements. The battery is supplied as one piece and is matched to the electrical requirements of the TN500 and TN420 models. Laboratories and field teams performing water quality checks, process control or environmental turbidity analysis can rely on this dedicated cell to keep their meters operational. From manufacturer APERA Instruments, the T500-4 integrates into the instrument housing without adapters or modifications. Its 3,7 V rechargeable lithium chemistry supports repeated charge cycles typical of portable laboratory equipment. Keeping a spare battery on hand reduces downtime between measurement series and ensures continuous availability of the turbidity meters. The product is suitable for both benchtop and portable use scenarios where the TN500 or TN420 instruments are employed for routine or compliance testing of water and process samples. Easy installation further simplifies maintenance routines in busy laboratory environments.

Questions about T500-4 rechargeable lithium battery for TN500 and TN420
What is this article?
T500-4 rechargeable lithium battery for TN500 and TN420 is the article on this page. Luminix Health distributes APERA Instruments for laboratory use. It sits in Lamps, cuvette holders & accessories, inside Spectroscopy & photometry, in Lab instruments.
A spectrophotometer's lamp, deuterium for UV and tungsten for visible, is a consumable with a life in hours. A cuvette holder sets the path. A 10 mm holder does not correctly read a 1 mm cell unless the software is told. The accessory has to fit that optical bench.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
