The second-hand devices are verified by Labexchange Service GmbH before delivery. You are receiving only fully functional devices.

Dispatch time

The stated dispatch times are the shortest possible ones for each article. The effective dispatch times can vary. The effective dispatch times will be stated in the order confirmation.

As a matter of principle, we are offering collective deliveries. The shipping time is calculated based on the position with the longest lead time. A partial delivery is possible on explicit request.

Shipping methods

Parcel services, forwarding agencies, self-pickup, delivery by Labexchange fleet.

Delivery information

Prices exclude shipping costs. Stated shipping costs are to be expected. Deviations are possible. If transport costs are not specified, please ask separately for them.

The stated transport and packing charges apply to the most favorable route if transport and are to be understood as subject to verification due to unexpected cost increases. By reason of unpredictable events, cargo rates and delivery times can change at any time and therefore have to be adapted to the recent situation. Import formalities and possible customs charges will be borne by the purchaser. Incoterm coding according to Incoterms 2010: For persons who collect the devices themselves: EXW, for dipatch by sea: CFR, by air freight: CPT, other shipments: DAP. Note for international shipments: A proof of preference/EUR1 will not be issued by us. When self-collecting/ordering EXW from countries within or outside the European Union, 16% VAT will be retained as a deposit until we have received the corresponding confirmation of arrival/bill of delivery from the buyer.

DESCRIPTION

The Model ZRF non-dispersive infrared (NDIR) analyzer features high accuracy, multi-functions and ease of operation through the use of a micro processor. lt utilizes a mass flow detector which is noted for its high sensitivity and reliability for analyzing one ortwo infrared absorbing components. In addition, the ZRF has a zirconia sensor (ZFK3) for measuring oxygen asthethird component orthe ability to receive a linearized 0-1 VDC signal from any external analyzer calibrated to 0-25% 02.

METHOD OF OPERATION

The infrared beam emitted from the source passes through a rotating single-point chopper which is cycling at 9 Hz. The energy is then split by a distribution cell into two beams which pass through the sample cell and reference cell. The distribution cell may also act as an interference filter if required. The reference cell is filled with a non-absorbing gas and the sample cell contains the infrared absorbing component.

The two infrared beams, one attenuated by the sample and the other not attenuated, simultaneously fall an the unique micro-flow detector which converts the intensity difference into resistance change. The 9 Hz AC signal is amplified then rectified to a linear 1 volt or 4 to 20 mA DC signal output.
