Why order the BOA311 from LabSupplies.com
Key Features
- Jet stirring: circulates silicone oil for high temperature-distribution accuracy, holding ±0.2°C and ±0.1°C accuracy at 200°C.
- Triple overheat prevention: automatic shut-off at set point +6°C, an overheat-prevention device, and an independent overheat-prevention device.
- Float-switch protection: dual float switches guard against empty heating and oil overflow.
- Emergency safety: emergency-stop switch forces cut-off of the overcurrent circuit, backed by an overcurrent leakage breaker and key lock.
- Digital control: green 4-digit LED shows the reading, red 4-digit LED shows the set point, with menu and ▲▼ key entry.
- Connectivity: external alarm output, temperature output (4–20 mA / 1–5V), RS485 communication, self-diagnostic and power-failure compensation functions.
How to Choose the Right Oil Bath
- Temperature range: this bath reaches room temperature +10°C to 270°C, so verify your protocol stays within that window with silicone oil.
- Voltage: the 220V configuration ships with an external transformer; match it to your bench circuit and available power.
- Footprint: Packed for shipping it measures 36 × 36 × 30 in at 130 lb.

Frequently Asked Questions
What is the temperature range of the Yamato BOA311 oil bath?
The BOA311 operates from room temperature +10°C up to 270°C. PID microcomputer control with a Pt100Ω platinum sensor maintains ±0.1°C accuracy at 200°C using silicone oil.
What is the reservoir capacity and footprint?
The reservoir holds approximately 37 liters. Packed for shipping it measures 36 × 36 × 30 in at 130 lb.
What voltage does the BOA311 require?
This configuration runs on 220V and ships with an external transformer. Confirm your bench circuit supplies the required power before installation.
What safety features protect against overheating?
Triple overheat prevention safeguards the bath: automatic shut-off at set point +6°C, an overheat-prevention device, and an independent overheat-prevention device. Float switches prevent empty heating and oil overflow, while an emergency-stop switch cuts the overcurrent circuit.
Does the BOA311 support external communication or monitoring?
Yes. The unit provides external alarm output, a temperature output terminal (4–20 mA / 1–5V adjustable), and RS485 communication, plus self-diagnostic and power-failure compensation functions.
What is the UNSPSC code for the Yamato BOA311?
The Yamato BOA311 is classified under UNSPSC 41103707 (oil baths).
Where is the Yamato BOA311 manufactured?
Yamato Scientific lists Japan as the country of origin for the BOA311.
Is there a spec sheet or brochure for the Yamato BOA311?
Yes. The Yamato BOA Series Oil Bath brochure (259 KB PDF) is linked under Documents & Downloads on this page.
How accurate and uniform is the temperature in the Yamato BOA311?
Yamato rates the BOA311 for temperature accuracy at ±0.1°C (at 200°C, silicone oil) and temperature distribution at ±0.2°C (at 200°C, silicone oil).
