Let’s Dive into VWR Vwr Spirit Precision Thermomet 4/1105
The VWR Vwr Spirit Precision Thermomet 4/1105, manufactured by Advantech Manufacturing, is presented as a certified blue spirit bottle freezer thermometer. Its key features include a measurement range of -25 to -5 degrees Celsius and certification at -20 and -10 degrees Celsius, promising precision in critical temperature monitoring. The inclusion of glass beads within the bottle adds another layer of interest, potentially impacting thermal behavior.
My need for a dependable freezer thermometer stems from years of experience dealing with inconsistent temperature readings in field refrigeration units. In my line of work, improperly stored medications or samples can lead to significant losses, demanding unwavering accuracy. I was looking for a thermometer that could provide reliable temperature readings, especially in extremely cold conditions, and the VWR Vwr Spirit Precision Thermomet 4/1105 seemed to fit the bill.
Upon unboxing the VWR Vwr Spirit Precision Thermomet 4/1105, my initial impression was one of sturdy, albeit basic, construction. The thermometer is contained within a protective bottle, filled with glass beads; it felt robust enough to withstand handling within a freezer environment. The included “statement of accuracy traceable to NIST and serial numbers” provided immediate reassurance about the thermometer’s calibration standards.
Comparing the VWR Vwr Spirit Precision Thermomet 4/1105 with other thermometers I’ve used, such as digital probe thermometers and standard bi-metal coil models, revealed potential advantages. Digital thermometers, while precise, are susceptible to battery failure and environmental interference, while bi-metal models can lack accuracy in extreme temperatures. I chose the VWR Vwr Spirit Precision Thermomet 4/1105 hoping its analog design would offer greater reliability in the long run.
My first impression was cautiously optimistic; the certification offered peace of mind. The glass bead bottle seemed a bit odd, making me wonder if it would impact response time.
Real-World Testing: Putting VWR Vwr Spirit Precision Thermomet 4/1105 to the Test
First Use Experience
I tested the VWR Vwr Spirit Precision Thermomet 4/1105 in a commercial freezer unit used for storing temperature-sensitive medications during a field deployment. The freezer was subjected to varying ambient temperatures throughout the day and night. I placed the thermometer inside the freezer, alongside a calibrated digital thermometer for comparison.
The VWR Vwr Spirit Precision Thermomet 4/1105 performed consistently under fluctuating ambient temperatures. The readings remained stable, and correlated well with the digital thermometer, staying within the stated accuracy range. The glass bead bottle didn’t seem to hinder the thermometer’s response to temperature changes.
The VWR Vwr Spirit Precision Thermomet 4/1105 proved easy to use; simply place it inside the freezer and observe the temperature reading. I did not need to calibrate or adjust anything.
Initially, I was surprised by the slow response time compared to digital thermometers. It took a few minutes for the VWR Vwr Spirit Precision Thermomet 4/1105 to register temperature changes accurately.
Extended Use & Reliability
After several months of continuous use, the VWR Vwr Spirit Precision Thermomet 4/1105 continues to provide reliable temperature readings. The blue spirit column remains clear and easy to read.
I have observed no signs of wear and tear. The glass bottle is robust and scratch-resistant.
The VWR Vwr Spirit Precision Thermomet 4/1105 requires minimal maintenance. I occasionally wipe it down with a damp cloth to remove any condensation or ice buildup.
