YOKOGAWA SR1008B62 Industrial-grade miniature recorder
The YOKOGAWA SR1008B62 is a high-precision, industrial-grade micro-recorder from the legendary SR1000 series.
It is a 6-channel dot-printing recorder designed to monitor and document process variables like temperature, pressure, and flow in real-time.
1. Introduction
The SR1008B62 is a compact, digital-display strip chart recorder. Unlike newer paperless recorders, this model uses a physical ribbon and chart paper to provide a permanent, tamper-proof record of industrial processes.
The “B” in the model name often denotes a specific revision or feature set, while the “62” typically indicates a 6-channel configuration with specific input/output options.

3. Product Advantages and Features
Universal Inputs: Each channel can be independently configured for different sensor types (e.g., Type K thermocouple on Ch 1. 0-5V DC on Ch 2) via the front panel.
High Visibility: Features a bright VFD display that shows channel data, alarm status, and time, making it easy to read from a distance in dark control rooms.
Durability: Built with a dust-proof and drip-proof front door (IP54 equivalent), allowing it to survive in harsh factory environments.
Interactive Alarms: Supports up to 2 alarm set-points per channel, which can be linked to relay outputs for safety shutdowns.
Permanent Records: Provides a physical paper trail which is still a requirement for many regulatory compliance audits (e.g., FDA or environmental monitoring).
4. Application Cases
Heat Treatment: Monitoring multiple zones in an industrial furnace to ensure uniform temperature distribution.
Water Treatment: Recording pH levels, turbidity, and flow rates in municipal or industrial waste systems.
Food & Beverage: Documenting pasteurization temperatures to comply with health and safety regulations.
Power Plants: Tracking turbine bearing temperatures and steam pressures over long-term operation cycles.
5. Related Models (System Components)
To keep the SR1008B62 operational, the following consumables and accessories are typically required:
B9565AW: 6-color ribbon cassette (Standard for SR1000).
B9565AK: Z-fold chart paper (100mm width).
B9565DS: Replacement internal battery for memory backup.
6. Other Models in the Same Series
The SR1000 series varies primarily by the number of channels and the recording method (pen vs. dot):
SR1001: 1-pen continuous recording.
SR1002: 2-pen continuous recording.
SR1003: 3-pen continuous recording.
SR1006: 6-channel dot printing (Standard version).
SR10004: 4-channel version of the series.
