New Sensors for Chemistry

Three exciting new chemistry products offer greater versatility for your college chemistry investigations.

NEW Vernier Flash Photolysis Spectrometer

Vernier Flash Photolysis Spectrometer

Demonstrate the fundamental principles of photochemical reactions with the Vernier Flash Photolysis Spectrometer, the first transient absorption spectrometer designed specifically for education. Free software and experiments are available for download.

  • Spectral coverage: 450–750 nm
  • Temporal resolution: 100 μs
  • Includes a 600 nm filter and an empty filter housing that can be used with standard-size, third-party filters

NEW Pressure Sensor 400

Vernier Pressure Sensor 400

Our new Pressure Sensor 400 accurately measures absolute pressures from 0 to 400 kPa over a wide temperature range. The robust, metal fittings allow for a tight, leak-proof seal between the sensor and your reaction apparatus.

The accessories kit that comes with the sensor includes:

  • double-barbed, brass connector to fit flexible tubing
  • nickel-plated-brass, push-to-connect connector to fit more rigid tubing
  • two-foot section of rigid nylon tubing
  • two-foot section of flexible PVC tubing
  • tightening wrenches and plumber’s tape to ensure a tight seal

NEW Platinum-Cell Conductivity Probe

Platinum-Cell Conductivity Probe

The two-cell, platinum sensing element and epoxy body of the Platinum-Cell Conductivity Probe ensures greater chemical compatibility when measuring the conductivity of stronger acids and bases and non-aqueous solutions. It has a range of 0 to 2000 μS/ cm, and a switch to turn on and off temperature compensation, making it possible to investigate conductivity as a function of temperature. The Platinum-Cell Conductivity Probe is easy to use with its plug-and-play operation and has excellent accuracy. Two experiments for this probe, “Kinetic Analysis of the Hydrolysis of Ethyl Acetate” and “Investigating Fundamental Concepts in Solution Conductivity,” are available for free download.

Introducing the Sound Level Sensor

NEW Low-Cost Sound Level Sensor Makes Sound Experiments Easy

Vernier Sound Level Sensor

Sound level is an engaging topic in physics, physical science, and middle school classes, and it just got easier—and less expensive—to explore! Use the new Sound Level Sensor to quickly and accurately measure sound level readings in a variety of environments.

As a follow up to the sound study we described in the Spring 2015 Caliper, we took our new Sound Level Sensor around the Vernier office to measure reverberation times in various rooms, including our classroom. In each case, we turned on a radio that was tuned to produce white noise, started data collection, and then quickly turned off the radio. The reverberation time is the time required for the sound level to drop by 60 dB (a factor of a million). In most situations, the sound level does not drop that far because background sounds create a noise “floor.” However, by using Logger Pro to apply a linear fit to the falling sound level data, we were able to estimate the reverberation times for several rooms.

Table of Reverberation Times

Room Description Reverberation Time
Office Small, carpeted, enclosed 0.5 s
Cubicle Open, carpeted, high ceiling 0.75 s
Classroom Large, rubber floor, “sound clouds” installed to dampen reflections 0.9 s

With the release of this new sensor, we have expanded our options for collecting sound-based data to include both the Sound Level Sensor and the Sound Level Meter. The Sound Level Sensor is quick and easy to use and has a range of 60 to 110 dB, which covers the sound levels in a typical classroom. Its response is A-weighted, meaning it responds like the human ear to loudness, and it is accurate to ±3 dB. If you need a wider range (35–130 dB), greater accuracy (±1 dB), or a C-weighted response, the Sound Level Meter is the better choice.
