The conductivity sensor BT27i measures the ability of a solution to conduct an electric current between two electrodes. The conductivity sensor consists of a conductivity electrode and an amplifier. The sensor has three measurement ranges ... more

The BT34i dissolved oxygen sensor measures the concentration of dissolved oxygen in water samples. The sensor is automatically temperature compensated by means of an integrated thermistor. Disposable caps with pre-mounted membranes allow ... more

The ECG sensor BT36i measures voltages that are produced by the heart. These voltages are measured at the skin of the wrists and elbow through electrodes. The voltages are amplified by the sensor and filtered and transferred through an optical ... more

The heart-rate sensor, BT47i monitors a person’s heart beat. Each time the heart beats, an electrical signal is generated. This signal is measured at the surface of the skin by electrodes embedded in the chest belt of the sensor. The ... more

The radiation sensor BT70i detects alpha, beta and gamma ionizing radiation. The sensor outputs a pulse when decay is detected. Also, a clicking sound is emitted and a LED light flashes. The sensor is suitable to detect low-level radiation ... more

The humidity sensor BT72i measures relative humidity. The sensor consists of an integrated circuit, which uses a capacitive polymer to sense humidity. The holes in the sensor box provide air circulation. Range: 0 ... 100 % Resolution ... more
