Purchase Guide

1. Basic styles of higher plants leaves

System composition: fiber version host, fiber optic, light adaptive leaf clip, dark adaptive leaf clip, software, etc.

Note: Portable fiber-optic dual-channel modulated chlorophyll fluorescence instrument has both red and blue light

Dual-PAM/F Basic

2. Basic hanging sample measurement

System composition: general-purpose host, optical fiber, sample pool for suspension measurement, software, etc.

Note: When purchasing suspended samples to measure basic models, you can not choose a light adaptive leaf clip. It is recommended to choose a magnetic stirrer.

3. Other optional accessories

1, 2060-B: Arabidopsis leaf clip, 60-degree angle light adaptive leaf clip, used in conjunction with independent micro-photo quantum/temperature sensor 2060-M, especially suitable for measuring Arabidopsis leaflets.The prerequisite for use is to configure 2060-M.

2, 2060-M: Miniature photo quantum/temperature sensor, measuring PAR and temperature, can be connected to MINI-PAM and used independently, mostly combined with 2060-B.

3. MKS-2500: A magnetic stirrer configured for KS-2500, specially configured for KS-2500, is installed under the KS-2500, which drives the rotor inside the KS-2500 to stir the liquid sample.

4, 2030-B90: 90-degree angle fiber adapter, mounted on 2030-B or 2060-B, bringing the fiber to a 90-degree angle to the sample.
