The Yamato GL260 is a compact 10-channel data logger that pairs a 4.3-inch color TFT display with universal analog input on every channel, making it a portable choice for benchtop, process, and field measurement. All ten inputs are isolated and balanced, so thermocouples, DC voltage, and humidity sensors can be mixed on one instrument without cross-channel interference. Built-in ~8 GB memory plus an SD card slot supports long unattended runs, and the optional G-REMOTE cloud service adds browser-based remote control and data storage.

Application Profile
Channel count and input flexibility are the two constraints that usually decide a logger, and the Yamato GL260 answers both for small-to-mid measurement jobs. Ten isolated channels let you record, for example, several Type K thermocouples on a thermal profile alongside a couple of voltage-output pressure or flow sensors — no signal conditioners, no ground-loop chasing, because each channel is independently isolated and balanced. The 16-bit ΔΣ converter delivers 1/40,000 resolution across the selected range, which matters when you are resolving small millivolt-level thermocouple changes rather than just watching gross trends.
Two features make it a genuine long-run recorder rather than a spot-check tool: ~8 GB of internal memory (plus SD) and a memory-loop/ring capture mode, together supporting recordings that stretch from days to well over a year at moderate sampling intervals. At 500 g with a 4.3-inch color screen and battery-pack option, it also travels — a practical fit for validation runs, environmental studies, and equipment commissioning where the logger has to leave the bench.
Frequently Asked Questions
How many channels does the Yamato GL260 have, and can I mix sensor types? It has 10 analog channels, each isolated and balanced, so you can mix thermocouples, DC voltage, and (with the optional B-530 sensor) humidity on the same unit.
Which thermocouple types are supported? Types K, J, E, T, R, S, B, N, and C (plus the legacy W: WRe5-26). Voltage inputs span 20 mV to 100 V.
What is the fastest sampling rate? 10 ms, available on a single voltage channel; the minimum interval widens as you add channels (for example 50 ms across 5 channels, 100 ms across 10).
How much data can it store? Roughly 8 GB of built-in memory plus an SD card slot (SDHC up to about 32 GB). In GBD format a 10-channel run at a 100 ms interval records for months; CSV files are larger and record for correspondingly shorter spans.
Can I monitor it remotely? Yes — with wireless LAN (optional B-568) and the G-REMOTE cloud service you can remote-control the logger and store data from a browser. Cloud service carries an additional charge and is offered in limited regions.
Does it run on battery? Yes, with the optional B-573 battery pack (DC 7.2 V) or a DC 8.5–24 V supply via the B-514 cable, in addition to the universal 100–240 V AC adapter.
Ordering & Configuration
Pricing for the GL260 is quote-based; add it to your quote and our team will confirm current price, configuration (terminals, wireless LAN, battery), and lead time. Common companions — the B-568 wireless LAN unit, B-573 battery pack, and NIST or ISO-17025 calibration — can be quoted alongside the logger.
Warranty: Per Yamato standard terms.
Positioning: The Yamato GL260 is the portable 10-channel member of the GL family — pick it when 10 isolated universal channels, a 4.3" screen, and battery portability cover the job. Step up to the GL860 when you need a 7" display, RTD support, or channel expansion toward 200 channels.
