When you're choosing a data acquisition recorder, the first question is usually about the environment. Are you logging a process with control and monitoring in mind, or measuring pressure and temperature in a wet, tight spot? The Eurotherm NanoDac and the Madgetech PR1000-300-PSIG answer those two different needs.
Quick Verdict
If you need data logging and process control from the same unit, the Eurotherm NanoDac is the one to start with. If your job is pressure and temperature logging in a rugged package, the Madgetech PR1000-300-PSIG is the more specialized tool.
Comparison
| Eurotherm Nanodac | Madgetech PR1000-300-PSIG | |
|---|---|---|
| Price | USD 416.04 | USD 699.00 |
| Condition | Used | New |
| Primary role | Paperless recorder and process controller | Pressure, temperature and transient pressure logger |
| Connectivity and I/O | Ethernet, USB host, universal analog inputs, relay outputs | 1/4" NPT fitting, MadgeTech 4 software support |
| Physical and storage | Color display, data logging built in | Fully submersible, 4" tall, 1" diameter, stores 1.3 million readings |
Where Each Product Wins
Choose the Eurotherm NanoDac if your data acquisition recorder also needs to handle control work as well as logging. Its control-side features make it a better match for someone who wants one box to manage a process and record it.
Choose the Madgetech PR1000-300-PSIG if your installation is wet or tight and you need pressure and temperature readings from a self-contained logger. It is built around measurement in places where a larger control instrument would struggle.
Product Notes
Eurotherm Nanodac Invensys Recorder
The Eurotherm NanoDac is a genuine UK-made paperless recorder and process controller with a color display, a USB host port, Ethernet communication, multiple universal analog inputs, and relay outputs. That combination makes it a strong candidate if you want logging and control in one box at $416.04. The unit also comes with data logging built in, so you can track process trends without adding separate hardware. The catch is condition: this is a used unit that shows normal cosmetic wear, including light scratches and minor marks on the bezel. It came out of a working system, so the electronics are described as functional, but the exterior will not look new. If a fresh, unblemished finish is a priority, this recorder will require a little more patience with its appearance.
Madgetech PR1000-300-PSIG Pressure and Temperature Data Logger
The Madgetech PR1000-300-PSIG is a new electronic data logger that records pressure, temperature, and transient pressure through a 1/4-inch NPT fitting. It is rated from 0 to 300 psig and stores more than 1.3 million readings, with an internal temperature sensor spanning -40 to 176°F and an accuracy of ±2.0°C. At $699.00, it brings a fully submersible design and a compact 4-inch by 1-inch footprint. That makes it a suitable choice when the logger may be exposed to moisture or installed in a confined space. The tradeoff is its focused scope: this device centers on pressure and temperature logging, while the Eurotherm covers the process-control side of the job. If your workflow includes control functions, the Eurotherm is the one to lean on.
Final Choice by Use Case
Choose the Eurotherm NanoDac when your primary need is a data acquisition recorder that can also act as a process controller.
Choose the Madgetech PR1000-300-PSIG when your application calls for a pressure and temperature logger built for wet or tight locations.
