Product Overview

The KR‑317 digital thermostatic water‑bath series is benchtop laboratory heating equipment built for stable isothermal incubation and heating processing. It adopts PID closed‑loop temperature algorithm and PT100 high‑precision sensing element to deliver steady water‑medium temperature from ambient up to 100 °C.

Multiple configurations are offered: 1‑hole, 2‑hole, 4‑hole, 6‑hole, 8‑hole well‑type models, plus larger‑capacity tank‑style variants equipped with magnetic stirring and timing‑drain functions. Different chamber sizes satisfy small‑scale single‑sample experiments as well as multi‑parallel‑sample batch processing. This unit is widely used in biomedical labs, pharmaceutical institutions, colleges, industrial QC‑departments and scientific‑research institutes for reagent heating, sample immersion incubation, constant‑temperature distillation and concentration workflows.

Core Product Competitive Advantages

Premium anti‑corrosion chamber craftsmanship
Inner reservoir is integrally stamped from 304 stainless‑steel, resisting rust from long‑term water‑medium contact and easy to wipe clean. Outer cabinet uses cold‑rolled steel sheet with electrostatic spray finish for scratch‑proof surface and long service‑life under daily lab environment.
PID intelligent digital temperature regulation
PT100 high‑accuracy temperature sensor works together with micro‑processor PID control. Temperature deviation can reach ≤±0.5 °C on high‑end models. Dual‑digit LED / LCD panel shows real‑time measured‑value and set‑point simultaneously; parameter modification is completed via simple front‑panel push‑buttons.
Flexible multi‑model modular selection
Well‑type hole‑versions cover 1‑8 positions; interchangeable annular lids fit flasks, beakers and test‑vessels of various diameters. Large‑tank options integrate magnetic stirring, timing‑control and drain‑outlet, supporting uniform medium convection for special‑purpose thermostatic experiments.
User‑focused practical detail design
Detachable silicone‑rubber ring lids reduce heat dissipation and prevent water‑vapour escape. Built‑in over‑heat protection cuts heating output automatically under abnormal temperature rise to avoid dry‑boiling risk. Compact benchtop footprint occupies minimal lab‑bench space.
Stable continuous‑run performance
Optimised heating‑tube layout realises even heat distribution across water‑bath cavity, minimising local hot‑spot phenomenon. Suitable for long‑time unattended constant‑temperature incubation tasks for routine laboratory batches.

Standard Complete Test Operating Workflow

Pre‑Test Preparation
Place unit on level stable lab‑bench. Pour purified water into inner tank; water level must cover heating‑element to prevent dry‑burn hazard. Fit corresponding annular cover rings according to sample‑container outer diameter. Power‑on the instrument.
Temperature Parameter Setting
On digital panel input target working temperature. For stirring‑equipped tank‑models, configure timer and stirring‑speed as required. Allow water‑bath to heat‑up and reach thermal‑stabilisation before placing samples.
Sample Incubation Processing
Set glass vessels holding samples into annular cover openings, make‑sure vessel bottom is fully immersed under water‑surface. Keep lid closed as much as possible to reduce heat‑loss during constant‑temperature holding period.
Experiment Completion
After finishing incubation task, turn‑off heating output first. Wait for water medium to cool down moderately before removing samples.
Post‑Test Tidying
Drain residual water via drain‑port. Wipe stainless‑steel inner‑tank to eliminate water‑scale and liquid residues. Keep equipment dry for storage. Periodically clean tank interior to avoid limescale accumulation affecting temperature‑sensing precision.
