Choosing a data acquisition recorder usually comes down to three questions: what will you measure, how will you retrieve the logged data, and how much condition risk are you comfortable with? The four recorders in this guide cover temperature, humidity, and gauge pressure. One is a new logger without a sensor, one is a used portable unit, one is an app-based temperature/humidity logger, and one is an open-box pressure/temperature recorder. Matching those differences to your workflow matters more than any single specification.
Quick Take
The Inkbird temperature/humidity data logger is the app-connected option in this set. The Dickson DWE is a new logger, but the sensor itself is not included. The Vaisala RFL100 is a used, compact option. At the other end, the Monarch Instruments Track-It recorder adds gauge pressure and temperature logging.

| Gauge pressure and temperature logging | Track-It Gauge Pressure & Temperature Data Logger | Pressure parameter plus dual connectivity |
Product Notes
Dickson DWE Data Logger
The Dickson DWE is the new-condition option if you already have a sensor to go with the logger. The MPN is DWE, and the DicksonOne identity is carried in the name. The important caveat is that the sensor is not part of this purchase; the DWE logger is the item being sold, not a complete temperature and humidity sensor package. That makes it a fit for a setup where the sensing element is already available or supplied separately. If you want a new logger unit with the DicksonOne name, this is the one to start with.
Vaisala RFL100 Data Logger
This used Vaisala RFL100 pairs the RFL100 logger with an HMP110 temperature and humidity sensor, and its country of origin is Finland. The design is compact and portable, which is the main reason to pick it over a bulkier setup. Because the unit is used, the condition is what you are accepting in exchange for that portability. The model and MPN are both RFL100, so there is no ambiguity in the part. If you need a logger that is easy to move between locations and you are comfortable with pre-owned equipment, the RFL100 belongs on your short list.
Inkbird Temperature Humidity Data Logger
The Inkbird is the entry point on price in this comparison, and the measurement ranges show what it can track. Temperature covers -40°C to 60°C with ±0.5°C/±0.9°F accuracy, and humidity spans 0 to 99%RH with accuracy figures tied to the 20%-80%RH range. The model is IBS-TH2 and the condition is new. Interaction is built around the Bluetooth app, so alarms and history are managed through that interface. The trade-off is that the app is the main way to pull data, and the unit is designed around that phone-first workflow.
Track-It Gauge Pressure & Temperature Data Logger
The Track-It is the only logger in this set with a pressure parameter. It records gauge pressure from 0 to 150 PSIG and temperature from -20°C to 85°C, using two channels. The housing is 316L stainless steel with a 1/4" NPT fitting, and the logger can store up to 130,000 readings. Connectivity includes Bluetooth (BLE) and USB. The model number is 5396-0371 and the condition is new open box. What you trade for that capability is the open-box state, so the condition is the main thing to weigh before choosing it for a critical logging job.
Final Recommendation by Use Case
- If you want an app-based temperature/humidity logger, the Inkbird Temperature Humidity Data Logger is the direct pick.
- If you already have a sensor and need a new recorder unit, the Dickson DWE Data Logger is the match.
- If a portable used unit is your priority, the Vaisala RFL100 Data Logger fits.
- If you need gauge pressure and temperature logging, the Monarch Instruments Track-It Gauge Pressure & Temperature Data Logger is the one to consider.
