Why order the BM302A from LabSupplies.com
Water Bath Digital 5L Overview
A flat-bottom reservoir with no internal heater or sensor keeps the φ240 mm bath easy to drain and clean. Heating runs through a 1000W aluminum-sheathed heater, while a Pt100Ω sensor feeds PID control managed by an onboard microprocessor. Setpoints enter through keypad and read out on a white LED digital display down to 1°C.
Key Features
- PID microprocessor control: holds setpoints across ambient +10 to 90°C with ±1°C accuracy.
- White LED digital display: keypad entry with a minimum display digit of 1°C for clear, repeatable setting.
- Easy-clean flat bath: 5 L reservoir with φ240 mm internal diameter and no heater or sensor inside the tank.
- Layered safety system: automatic and independent overheat prevention, temperature upper-limit error detection, and an overcurrent protection fuse.
- Flexible operation modes: fixed temperature, quick auto stop, auto stop, and auto start.
How to Choose the Right Water Bath
Selecting a water bath comes down to matching reservoir volume, temperature performance, and site power to your protocol. Use these axes to confirm the bath fits both the workflow and the bench.
- Voltage: choose BM302A for 100-115V mains or BM312A for 200-230V mains to match your facility's supply.
- Footprint: Packed for shipping it measures 16 × 16 × 14 in at 16 lb.

Frequently Asked Questions
What temperature range does the Yamato BM302A water bath cover?
The BM302A operates from ambient +10 to 90°C with ±1°C accuracy. Temperature is regulated by PID control through an onboard microprocessor and a Pt100Ω sensor.
What is the bath capacity and reservoir size?
The bath holds 5 L and has a φ240 mm internal diameter. The reservoir is a flat design with no heater or sensor inside the tank, which simplifies draining and cleaning.
What is the difference between the BM302A and BM312A?
Voltage is the only difference. The BM302A runs on 100-115V mains and the BM312A runs on 200-230V mains; both share the same 5 L capacity, temperature range, and control system.
What heater and safety features does this bath include?
A 1000W aluminum-sheathed heater provides heating. Safety devices include automatic overheat prevention, independent overheat prevention, temperature upper-limit error detection, and an overcurrent protection fuse.
What are the dimensions and weight for bench planning?
Packed for shipping it measures 16 × 16 × 14 in at 16 lb. Confirm bench clearance near a power source and drain before installation.
How are temperature settings entered and displayed?
Settings are entered by keypad and shown on a white LED digital display with a minimum display digit of 1°C. Operation modes include fixed temperature, quick auto stop, auto stop, and auto start.
