CBL - Calculator-Based Laboratory System

Connects to TI-73, TI-82, TI-83, TI-83 Plus, TI-85, TI-86, TI-92 or TI-92 Plus.  Easy way to collect and analyze real world data; can be used as stand alone data collection device; Five channels for data collection to measure motion, temperature, light, pH, force, EKG, dissolved oxygen, sound, pressure, and more with appropriate probes; CBL Kit includes 3 probes (temperature, light and voltage); impact-resistant carrying/storage case.

TI - CBL Probes / Sensors & Adapters

CBR - Calculator-Based Ranger - Motion Detector that can be used without the CBL - connects directly to the TI-73, TI-82, TI-83, TI-83 Plus, TI-85, TI-86, TI-92 or TI-92 Plus; connects to CBL (or other CBR's) for use with other probes.

Pressor Sensor - Use for gas experiments in chemistry, physical science, and physics.  It has a range of 0 to 100 psi (0 to 6.8 atm) absolute pressure.

Motion Detector - Functions like the automatic range finder on a Polaroid camera; detects and emits ultrasonic pulses and waits for an echo to calculate distance, velocity, and acceleration.

pH System - Includes a pH electrode (Ag-AgCl combination with a range of 0 to 14) and pH Amplifier (contains the signal-conditioning circuitry).

Dissolved Oxygen Probe - Use to determine the concentration of oxygen in aqueous solutions in the range of 0-13 mg/L (ppm); built-in temperature compensation and a fast response time.

Microphone - Use to display and study waveforms of sounds from voices and musical instruments.

Colorimeter - Use to survey stream or lake habitat; determining water hardness; photosynthesis.
