Bluetooth Optical Probe OP-730

Optical Probe


The OP-730 Optical Probe is an interface that communicates via infrared waves with a peripheral device such as an electricity meter, water meter, heat meter, gas meter or any other device that has an optical port on it. It incorporates a small housing design that makes it rugged with its Aluminum and Polycarbonate filter material. All devices that support the European standard IEC62056-21 (IEC 1107) Mode E & C and IEC62056-31 will work with this product. In addition, it has the capability to send settings for data transmission with all types of IEC meters in transparent mode.

OP-730 has a Bluetooth connection interface, which is suitable for tablets and mobile phones and all devices with a Bluetooth connection availability. It is compatible with Windows and Android operating systems. It derives power from the internal rechargeable battery, so there is no need for external battery pack or AC adapter. OP-730 benefits from a very strong magnet that firmly attaches the optical probe to the meter and also has resistance to external light influences other than the infrared wavelength. Installation and configuration instructions are included with the probe.

Ergonomic & User-friendly Housing Design

The housing is designed to be fit in the hand of the user easily and the material used makes it strong and also light weight. It is resistant against surface wear off in long term usages that is caused by using the optical head on the meters and devices with optical port installed on them.

Good material not always brings good hardness. The housing shape can have tremendous effect on the hardness of the probe. We have designed the optical probes to withstand falling from one meter height, in case it slips from user’s hand.

Powerful Magnet

The head contains a powerful magnet on under the surface in which the probe is attached to the optical port, that causes the probe to stick to the optical port and not easily removed, in order to secure connection to the device and let the user work without needing to hold the probe in position with one hand.

Warning: due to strong magnetic force of the magnet used in the probe, please do not store it beside electronic equipment, because it can damage these devices in long time storage. It also causes malfunction in any storage device like hard drives, solid-state memories (flash memories, SSD drives and etc.), RAM storages and etc.

Optical Filter

In order to be able to communicate between the two devices through optical port, certain wavelength must be used. The wavelength used must be in the range of 880 nm infrared light that is not visible to the human eye. The light filter used in this optical probe filters all ambient light, preventing any disruption to probe communication, thus providing stable and efficient communication between two devices.
